commit f22ce4ebc91494fbe3eb7889d1f5bd47d642bce9
Author: Juan Pablo Ugarte <juanpablougarte gmail com>

Made glade-previewer monitor css file and display parsing errors in a GtkInfoBar.
Created new GladePreviewWindow widget and lots of cleanups.
Improved screenshot option, save screenshots in any GdkPixbuf supported format.
Added options to take vector screenshots (F5 svg, F6 ps, F7 pdf) and F8 png
