Editors not gaining focus when changing by tab click

[goanpeca]

With 2 or more files open on the editor, clicking on different tabs should give the focus to the editor (cursor should start blinking) and the outline explorer should update because of this focus gain. Currently the focus is not given to the editor. This does works with the file switcher.

This is on 3.x but not on 3.1.x.

@dalthviz, please take a look at this one. Since this is a bug that appeared in 3.x, please use git bisect to detect the commit that introduced it.

I introduced this bug in 2228e83 while fixing #1170, giving the focus to the Editor caused the unwanted scrolling, should we revert it?

@ccordoba12 ?

No, we should find a new way to give focus to the current tab. #1170 was very annoying.

@rlaverde, please work on this one.
