This will allow us to add remote-ids by hand and have them be saved between bumps.

The XML needs to be translated to a set of these:

hackport/src/Portage/Metadata/RemoteId.hs

Lines 63 to 78 in 4378443

	data RemoteId
	= RemoteIdHackage String -- ^ Hackage package
	| RemoteIdCRAN String -- ^ CRAN package
	| RemoteIdCTAN String -- ^ CTAN package
	| RemoteIdGentoo String -- ^ Gentoo project
	| RemoteIdGithub String String -- ^ Github user and repo
	| RemoteIdGitlab String String -- ^ Gitlab user and repo
	| RemoteIdLaunchpad String -- ^ Launchpad project
	| RemoteIdOSDN String -- ^ OSDN project
	| RemoteIdPECL String -- ^ PECL package
	| RemoteIdPyPI String -- ^ PyPI project
	| RemoteIdRubygems String -- ^ Rubygems gem
	| RemoteIdSourceforge String -- ^ Sourceforge project
	| RemoteIdVim String -- ^ Vim script
