core: trigger hooks
This MR makes pushing and pulling from Git trigger incoming, outgoing and changegroup hooks, along with the corresponding pre* hooks. In addition, the gitexport and gitimporthooks allow intercepting when commits are converted. As a result, this MR should allow using thenotify`` extension when interacting with Git repositories.
Fixes #402 (closed)
