Subject: [PATCH] Change the way the MAX_FILETYPES define works. It now
 allocates enough filetype icons as it needed last boot + 8, this means we
 should never have to edit the define again. If you get the "filetypes array
 full" splash, do a clean reboot and it shuold go away. if it doesnt make sure
 you file a bug report and let us know you did reboot and it stayed there...
 it means that define does actually need increeasing.
