[TxMt] Env vars

[Thomas Aylott (subtleGradient)]

Take a look at how I do this in TextMate/Support/lib/codecompletion.rb
look at set_line! and caret_placement

You have to take into account that tabs are only a single character of  
variable width and that the current selection could have started from  
the left or right.

It really is way more complex than it should be, hopefully TM2 will  
make this simple.
