[PATCH] Make cvs2git support remote CVS repos

Added a "--module=cvsmodule" command line option and (since we're going to process argv
anyway) made "-v" for verbose mode a command line option too, instead of a compile time
option.

I've tested it on some (small) private CVS repos and it *seems* to work, although some of
the initial commit ordering is wrong, but I think this is due to the commit time being
wrong within my CVS repo itself.

I didn't make author and email prettyprint, but I really want to make it a command line
option, the discussion from yesterday about whether prettyprinting should be at the
plumbing or porcelain layer notwithstanding.

Regards,
