mike-

your patch is much tidier than mine, thanks for fixing it up!  i really
like the removal of scmtype from the configuration file.  i'm mixed on
the removal of scmusername because i'm not sure that koji clients should
specify the username used by the koji builder to perform ssh checkouts.
however, while i thought it worth pointing out, it does not seem too big
a deal to disclose this username.

i did some testing with my svn+ssh repository and found the patch below
necessary- it creates ../common only if it does not already exist.

thanks again for adding this functionality to koji. :)
