Cleaned up some code and added some comments. Added in method to remove
an image from the cache because I may need this in the future.
Can now pickfanart from among extrathumbs when scraping JAV movies in
manual mode.
1. Nicer quality image scaling.
2. GUI will not crop poster read in from nfo anymore if there is no
local art.
Animated cursors while scraping now stays busy while waiting for fanart
picker dialog to load
