// Simple browser my attempt at an even less-sucking browser than surf.
//original code is from alot of places, gtkforums.com, gtkwebkit.org provided 
//alot of nice API examples :), and of course, surf (though i was careful not to steal any code because of the damned MIT/X license)
//uzbl also helped inspire me. along with a previous surf fork named inferno.
