Basic Go syntax highlight working, created a hacked QML Textarea working well
for tabs and got automatic indenting.
The editor is quite ready:
* Syntax highlighting working
* Tab indent working
* Other keyboard handlings
Add basic Undo/Redo functionality. Fix typing whitespaces resulting in
weird behavior, fix wrong behavior when going left and right.
