Use buffer not string

[basarat]

Lots of calls to getText on atom editor. Also our languageServiceHost specifically ScriptSnapshot is working on string. Make it use nodejs Buffer. Also do this when reading files etc.

Debounce linter further

Use on did change to just copy edit buffer.

And Debounce errors further

It is just might make autocomplete work as it is.

Not needed.

Investigating.

It seems like this is not the issue. The program.languageServiceHost.updateScript(filePath, options.editor.getText()); call only takes under 1ms on a 1000 line file (considered a largish file for most purposes).

However the complete call to requestHandler in autocomplete plus is around 100ms

With getCompletion taking the majority of time.

So moving this to the wishlist category.

TODO: investigate if getCompletions makes calls to the language service host and consider optimizations if that is what is taking too long.

Probably a good thing to do after #130

We are not going to use a buffer. Instead we will bring in the changes from TSServer
