Add /usr/local/share/icons to the list of icon directories

Hi,
same thing as #5, for icons this time. Sorry that I didn't think about it before.

Sorry. This is not something that I can accept, as it decreases the performance of the script with no real benefits for all users.

Considering that a user might have two or more icon themes installed under /usr/local/share/icons, traversing the entire path not only slows down the script, but also populates the icon.db cache with useless entries, increasing its loading time.

I would say to leave this as something a user will add to he's config.pl file when it's really necessary. ;)

Ok, no worries, I didn't think so much :)
