[crossfire] python version check

[Andreas Kirschbaum]

No feedback, therefore I'll assume that it's ok to commit these changes.

Unfortunately I get lots of differences after running the autogen.sh
script: The files aclocal.m4, configure, and all Makefile.in have
differences.

The differences in Makefile.in are minor (a few added lines like
"AR = @AR@").

The differences in configure probably are because I use autoconf version
2.59; the existing files are from version 2.57.

The differences in aclocal.m4 are huge even though I use the same
automake version 1.6.3 that was used to generate these files.


What should I do here? Just commit "my" files?
