Adapt to upstream changes - ChangeHooks is gone. Hooks are now invoked via the ref-update event. - The ref-update firing mechanism now needs the user - ProjectControl#canReadCommit now takes a Repository, not RevWalk - Repository#getRef is deprecated in favor of #exactRef The Buck build was already updated to build with 2.13-SNAPSHOT, but the pom.xml was still using 2.12-SNAPSHOT, so update that too.
