Replace all `which command` calls

The trouble with `which command` is twofold:
 - It spawns a whole shell just to find out the path to a binary, every time;
 - The results are environment-dependent, since they depend on $PATH. It would
   be better to specify the search path in the configuration file where everything
   else is specified rather than in the environment.

This commit replaces it with the new mechanism from AlaveteliExternalCommand.
