Gitolite integration

Couple of things there...

1. Any git repository can be used with devshop.
2. If your git repository host has configurable "post-receive callbacks" (i.e. "webhooks") it can be used to automatically trigger a "git pull". Any web request to your devshop project's "Webhook URL" will trigger a "Deploy Code" task on all environments that are set to track a branch. This works now.
3. If you use GitHub, you can use the "devshop_github.module", which means you get:
1. Improved "git pull" logic: When you push code to GitHub, their webhook sends the branch name. devshop will read this branch and will only trigger a code deployment on the environments on that branch, saving task cycles.
2. Pull Request integration: You can configure your project to create a new environment whenever a new Pull Request is fired for your environment.
3. Test status integration: If you use pull request environments, Deploy and Test tasks post status updates back to github, giving your developers links directly to the PR environments and displays test results.
4. Automatic SSH key and project webhook setup. Using the GitHub API, devshop can automatically post it's SSH key to your github account, giving clone access. It also sets up the github webhook URL automatically when you create a project, so you don't have to do it manually.
4. The devshop_pull.module (specifically devshop_pull.inc, line 42) handles the webhook requests. Right now it is not pluggable. The plan has always been to make it more pluggable so modules for other git providers could be written.
5. If you wanted to use that module in your devshop site, I don't see any prolem, except that it's for Drupal 6. We are rushing to upgrade devshop to drupal 7 since drupal 6 end of life is coming in 2016.

So, if you wanted to help, I'd start by refactoring the function devshop_pull_callback in devshop_pull.inc to use hooks or something to determine what other module to kick off to.

Thanks!
