Setup.hs: compile Alltenses before Present

When mkPresent (or another preprocessor) is used, error messages from GF will
show the file name _gf_preproc.tmp instead of the name of the file where
the error occurred. By compiling Alltenses first, the real file name will
appear in error messages (unless the error only happens then mkPresent is
used).
