Revert "Merge branch 'git_hook_messages'"

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.

CHANGELOG

-v2.4.0
-  - Show error message when git access is rejected
-
 v2.2.0
   - Support for custom hooks (Drew Blessing and Jose Kahan)
