Subject: [PATCH] Revert my filetypes commits from today. the nvram buffer is
 44bytes of which 43 are currently being used. We need to figure out what to
 do about this. So in the mean time, set the MAX_FILETYPES to a huge value so
 we don't have to worry about this for a long while.

This build shold be safe to use again. If you downloaded a build after r14286 make sure you grab a new one
