Subject: [PATCH] Gedit word select doesn't include space

Bugzilla bug 634956
When dragging a word the space is not dragged with it.
This patch checks the source and destination of the drag.
If both source and destination have a space near them it will try to
extend the select to a space near the source to preserve the tokens.
Add function gedit_view_drag_data_text_recived to gedit-view.c to
handle the drag and drop of text.
