It is necessary to wrap some paths in CKEDITOR.getUrl()

Are you reporting a feature request or a bug?

Improvement

Provide detailed reproduction steps (if any)

1. Load any page with CKEditor
2. Open browser dev tools
3. Make sure some loaded files (like tableselection.css) have no timestamp query param

Expected result

CKEDITOR.getUrl() is always used to load any editor source.

Actual result

Some plugins (like tableselection, widget, scayt) don't use CKEDITOR.getUrl(). In common case, it is inconsistency and it prevents cache reset. In our case - we override CKEDITOR.getUrl() behavior by window.CKEDITOR_GETURL() - it prevents loading of some resources at all.

@mlewand Would you accept a PR to add CKEDITOR.getUrl to the tableselection plugin?

Images referenced within CSS are still an issue though – could a build step be added that appends the timestamp to all image URLs within CSS files? (Edit: I see that this is already done with the editor.css file.)
