Added new dialogs to import and export volumes
groups.

version 0.4.4
The lvproperties widgets have a little bit diffent
look now. Small bug fixes. Lvcreate now has a name
validator.

Added more information the the pvproperties widgets. 
They now use a QTableWidget to show the extents

Fixed a bug that caused random crashes after 
mounting/unmounting and certain other operations.

now.

Still doing coding style unification and hunting
down small bugs. Extending non-linear volumes should
work better now.

More additions for handling mirrors. The "properties"
widgets improved again and background colors made to
match. Many bug fixes.

Changes to the handling of mirrors, still not done.
