Change column resize mode to interactive and stretch last column, so there's no useless space on the right. Also minor fix to sorting last_timestamp column, for more readability and also to fix a rare bug.
Everything that should work works. Further improvements that would be nice:
- replace untidy multitude of QtGui Items with one generic type
- restore Qubes Network functionality
- add Boot From Device action (and easy way to install windows tool from there)
