Mostly code cleanups related to commits in past two days.

* Replaced custom function FIND_PATH with AC_PATH_PROG, used for finding sdl-config.
* Removed -lphysfs from Makefile.am which should be added automatically already.
* Actually show the overweight message, and only show it once for each time weight
  goes above half the max weight.
* Surfaces passed to SDL_BlitSurface shouldn't be locked according to the manual.
* Minimal fps limit is now 10 fps.
* Reverted change by Bertram that hardcoded the updatehost value.
