* pkgs: refactor needless quoting of homepage meta attribute
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
lxappearance supports both Gtk+-2 and Gtk+-3. The current `lxappearance'

A patch is needed in order to look for themes in system data dirs with
Gtk+-3.
