Commit 5de079b8 by Vicent Marti

Change the object creation/lookup API

The methods previously known as

	git_repository_lookup
	git_repository_newobject
	git_repository_lookup_ref

are now part of their respective namespaces:

	git_object_lookup
	git_object_new
	git_reference_lookup

This makes the API more consistent with the new references API.
