Bundlemerge optionally takes a completed plist to bundle into the archive, instead of multiple plists to merge and variable substitutions to apply.

The new key bundle_info_plist_file, gives the path to the completed plist.  If it is defined, the keys source_plist_file and variable_substitution are not used.
