 MSN ApplicationId patcher for pidgin/bitlbee/whatever
 (because you're too lazy to rebuild the whole thing.)

 Usage examples:

    python patch.py /usr/sbin/bitlbee
    python patch.py /usr/lib/purple-2/libmsn.so

 It will output the modified file to the current directory.
 Backup the original file and replace it with the new version.

 If you're lucky, it will work.
 If not, don't be lazy and rebuild it.
