Created a new helper to assist in our transition to Symfony Process components: devshop_drush_process();

- Cleaning up empty rows of dothooks commands.
- Using brackets from Drush logs to create nice looking hook "type" labels.

- Output git status.
- Make sure to throw a drush error if an exception is thrown.

- Re-writing post DL hook to use GitWrapper instead of provision-git.

Cleaning up drush_run_acquia_hook(), it works now with devshop, despite the differences between the script arguments for project and environment

Conflicts:
	acquia/acquia.drush.inc

Adding a "manual" drush option passthrough to devshop deploy so that acquia hooks post-code-deploy is possible.

Switching to checking for a missing environment. This is the exact moment that the clone's updatedb is going to run.

Adds the "registry-rebuild" call to a "clone" task run.
