Better git hook messages

DZ already merged it but we had to revert it because of lack of time to deploy to dev.

See merge request !48

This reverts commit f8453da5.

At least the following things were broken:
- missing require for 'gitlab_access_status' in lib/gitlab_net.rb
- gitlabhq master internal API returns 'true' or 'false', gitlab-shell
  expects JSON

This reverts commit 11311a95, reversing
changes made to 45444597.

Add custom hook support to CHANGELOG

Custom hooks

- Reset G_ID if the custom pre-receive hook fails
- Use a pipe to feed stdin to the custom pre- and post-receive
  hooks, in the same way that the standalone git works

fixing broken custom pre-receive calls

when a user has access. Doing an exit 0 effectively ended the
thread. No code would be executed after the call to exec.

This changes fixes the problem for the pre-receive hooks but you want
to check that GitlabAccess.exec is not used elsewhere. A quick
grep of the code seems to indicate this is not the case

Add optional repo path, remove reference to gitolite repo

avoid @user_tried

Added list-keys command, with associated spec

Added list-projects command & spec
