Also markup file system names as GUI menu items.
Bug #688882 - Improve clearing of file system signatures
Restructure and word-smith translatable text associated with the
enhancement to add ability for setting UUID in an effort to better
align with the Gnome Documentation Style Guide.
See Bug #667278 - Add support for setting UUID
Add the ability to set a new random UUID on file systems that provide
the appropriate tools to perform this action.
Update the help manual to include this new functionality. Also add
reference links to "setting a partition label" and "changing a
partition UUID" in the "copying and pasting a partition" section.
This patch does not include setting the UUID on an NTFS file system.

To further minimize the chance of accidentally creating a new partition
table, the following steps have been taken:
1) Rename non-standard Create button to stock Apply button.
2) Remove extra warning about erasing entire disk device.
3) Update GParted Manual accordingly.
