[gedit-list] Auto-closing brackets in selected area

["Jorge Cob" <jorgecs10 gmail com>]

Hi, this is my first post in the list.
Christiano Farina Haesbaert ask about a plugin that can enclose text
in brakets, sometime ago. I wrote a plugin that do exactly that
sometime ago, so i decide to share it.
it's in python, i attach the files.

some notes on gtbtextwraper:
in my pc this module is in other directory, thats the reason i modify
the python path in the plugin so i can import it, feel free to edit it
