icon theme bugs

[Brian J. Tarricone]

ok, all this should be fixed now.   a couple dumb mistakes that just 
took a while to track down (freeing memory, not setting the pointers to 
NULL, and then checking them later = bad).  i did some more testing and 
experimenting and tweaking, so it should be quite a bit smarter about 
finding the best matching icon at the best size.  i'm actually quite 
pleased with myself ^_~.

for some reason, now i'm getting a bunch of:
*** attempt to put segment in horiz list twice
printed to stderr while generating the menu.  they appear to be 
harmless.  i can't be 100% certain, but i _think_ this might be 
SVG-related.  anybody have any clues?
