[horde] Icons as PNG-format

[Mats Djärf]

It would be great if PNG should be the standard format for icons etc in 
Horde. Just because transparency is much better in PNG than GIF-images.
It's pretty hard to get smooth icons in GIF-format when same icons is 
used in top-menu, side-menu or header section when the background is 
different.

If GIF-format is written in stone, then one solution is to have specific 
icons for top-menu, side-menu and header section. The icon size can also 
be different with this solution.
I know that _Joaquim_ mention a solution in this mailinglist with three 
kind of icons. "Small, medium, large" and this is same as specific icons 
for top-menu, side-menu and header section.
