A lot of packages are needlessly quoting the homepage meta attribute
(about 1400, 22%), this commit refactors all of those instances.
* pkgs: Fixing some links that were wrongfully unquoted in the previous
commit
* Fixed some instances
- Replace non freedesktop `CAD` desktop category
by categories taken from debian's desktop item.
This make the desktop items appear under the
`Graphic` category in DE menus instead of `Others`.
- Moved to new package icons as specified by
upstream release notes.
- Moved to icon name instead of full path to
a single icon as specified by freedesktop
specification.
- Human readable desktop item names.
