DriveSetup partition list has too many columns

[pulkomandy]

The DriveSetup UI tries to show every possible details about partitions in a column list view. But we have a lot of things to show, and some information gets pushed out far to the right, and in general this makes things little visible.

Instead we should have a much simpler list with only the key info:

• Filesystem name if available, or partition name, or device path
• Size
• Status: formatted (with filesystem name) or not formatted

There can be an additional panel below or to the right of the partition list, that would display full details of the currently selected partition (block sizes, etc) and maybe a few action buttons (edit, delete, ...)
