[TxMt] Improvement: Set focus to editor after Drag&Drop operation

[Christian Schwanke]

Hi,

I just managed to create a custom Drag Command that works similiar to 
the IMG-Dragging in HTML-Mode.
However, after dropping a file, TextMate inserts the correct code but 
the focus stays with the project Drawer.

Since I insert the code as a snippet, I have to press Shift+Tab in order 
to focus the editor pane before I can step through the different 
snippet-variables. So please, set the focus to the editor pane after 
drop-events or at an option to configure this behaviour.

I'd also like to see a popup displaying the various auto-completion 
options instead of the ESC-cycle solution.

Thanks in advance,
Christian
