Merge lp:~stewart/drizzle/remove-datahome-catalog into lp:~drizzle-trunk/drizzle/development

[Stewart Smith]

Remove getDataHomeCatalog(), which means we produce "local/" in the path in a couple of places which is kinda nice, gets us a step closer towards multiple CATALOGs.

We instead use catalog::local_identifier() around the place.

I also lay some groundwork inside the schema engine.

What are the rules for the copyright lines?
Should one add one's name to every file one edits?
