Vineyard update

Sorry for the lack of updates lately, lot's of stuff to take care of lately, but at least Vineyard is shaping up nicely! It took a bit longer than I expected to rewrite Vineyard, most of it was due to the code redesigning but the porting from Glade to code definitely also took longer than anticipated. What you can expect from the next version is much, much, much faster start up time, "lazy loading" of pages and better error handling. So far the only pages that need work are Drives and Programs - the last one needs some more redesign on the python-wine end as well, so it'll take a little while, but it should prove much faster when done (it already is). I've reorganised the pages a bit, to hopefully make it easier to navigate.
