Subject: [PATCH] Add support for ':' in the profiles parent file for bug
 414961.

Bug #414961 allows ':' shorthand to resolve to the ${PORTDIR}/profiles
A value before the ':' references the repository, no value means
gentoo

Example: local:base would refer to the profiles directory in the
repository path owned by the 'local' repository
