This pull request adds a widget upload feature.

It can be hooked to any widget.

Allowed accepted file types can specified using supportedTypes property in widget definition (similarly as it is in uploadwidget).

Also allows for easy progress bar customization by progressReporterType property in widget definition.

It also fixes several other issues:

Misplaced progress bar (tp3350).
Misplaced balloon toolbar after initial image load.

I have targetted this PR into a upload widget feature branch, as it still needs undo integration before being merged into EI feature.

This is done as a temp workaround, as the objects that we're passing as definition to features, are copies of the original definition. In other words any modifications to definition done at runtime (by other features setUps or at a widget runtime) are not available in setUp function. Because of that definition.name was not available (because it's assigned by the widget system at a widget construction time).

Pushed a set of fixes that also brings:

Fixes requested in review summary/comments.
Support for pasting images from clipboard in IE11 tp#3390
Support for pasting a single image file in Firefox tp#3390
Support for converting any pasted base64 encoded image.
- This also handles images pasted from Word.

This PR does not cover following cases:

No improved support for switching to source mode and back during upload, so that following is not yet satisfied:

Switching to Source mode during upload also results in widget with not updated blob URL (previously it caused errors so it is an improvement).
No handing for cross editor copy and paste widget during upload to other editors (it will remain a blob reference).

These limitations will be addressed in future releases.

Just few things to polish:

Language files were not regenerated.
As support for PFW was added, it would be nice to add some tests covering it (manual for sure, unit test maybe, WDYT?):

Support for converting any pasted base64 encoded image.

This also handles images pasted from Word.

Small issue with circle progress reporter - as it creates some overlay over image during upload it is not possible to edit caption during upload.
Direct image paste works funny on OS X, but I suppose it is an OS "feature":

It somehow a little less consistent, but from practical point of view makes much sense. Let's leave it as is 👍

Shouldn't it be

This type serves solely as a mixing, and should be...

?

Also, I think we should add @since tag here.

As for @since tag, I don't see much sense for that here as CKEDITOR.plugins.imagebase namespace is added in 4.9.0 so it seems natural to me that this info is not needed.

I'll report a feature request in Umberto to inherit/"cascade" since tag.

FYI: reported as cksource/umberto#466

I was thinking about making it more consistent (Method to be called versus To be called), but I think something like Marks the progress as complete. or Refreshes the progress. sounds better, WDYT?

Great idea! It's simpler. The original text looks redundant compared to that.

I would change order of options.files and options.callback so the required one is first.

I have a mixed feelings about ProgressReporter instead of progressReporter, but I see what was the intention here.

Well we don't have an official and strict rule about this. My intention was to uppercase a local variable in case it stores a type. Does it make sense?

Makes sense, it may be a good way to distinguish it 👍

Language files were not regenerated.

Good point, however our lang tool seems to be broken, as I'm adding easyimage plugin to list of plugins tracked by lang tools and it still doesn't work. I'll extract it to a separate ticket, especially that original entries need a fix too.

As support for PFW was added, it would be nice to add some tests covering it (manual for sure, unit test maybe, WDYT?):

Support for converting any pasted base64 encoded image.

This also handles images pasted from Word.

As for manual test it's a good idea (added in 44e6f43).

As for unit test, TBH I don't find it necessary at this point. We have a good coverage with base64 encoded tests, and this is what our Paste form Word produces.

If we ever have some problem on integration between the two, we'll add a proper unit testing for integration.

Small issue with circle progress reporter - as it creates some overlay over image during upload it is not possible to edit caption during upload.

This is used just for tests, it's purpose is just to visualize the flexibility of this feature. It looks good enough as it is.

We'd have to worry about that if it was our main progress reporter.

Direct image paste works funny on OS X, but I suppose it is an OS "feature":

I don't have a Mac to check it at this point, but I suppose it transforms image into base64-encoded one, thus following feature apply:

Support for converting any pasted base64 encoded image.

Pushed fixes.

Looks good, nice work 👍

Looks like works according to the feature. The image (I mean the icon) is properly uploaded to CS.
