Tilda-0.09.2

This release includes many small bug fixes plus: a new configure backend (you'll need to either use the python script to convert your old config files or delete them and make them again), increase use of glib (glib 2.8 or greater is needed), no more blinking of the screen when hitting backspace, delete or tab multiple times, sliding action is added, and shortcuts for addings tabs and moving to the next and prev tab.
