Split ProjectQuirks out into its own file

ProjectQuirks is used by external quirks files and importing it from
vcs-to-changelog.py is broken since it was renamed to use hyphens.  It
is cleaner to put it in its own file anyway.

	* build-aux/vcstocl/projectquirks.py: A new file...
	* build-aux/vcs-to-changelog.py (ProjectQuirks): ...to which
	we move ProjectQuirks and import the file.
