[PATCH] cvsexportcommit: Create config option for CVS dir

[Trent Piepho <tpiepho@freescale.com>]

For a given project the directory used with the -w option is almost always
the same each time.  Let it be specified with 'cvsexportcommit.cvsdir' so
it's not necessary to manually add it with -w each time.
