Removed the provision_service function, and introduce service handler subscriptions in the environment objects.

Instead of provision_service('type') you now use d()->service('type') to access the service object.
The context object returned by d() now manages which context object's service to return, based
on the internally managed subscriptions.

stop the generation of drushrc.php when a site context is being saved.

 provision-named-context-save is now provision-save provision-named-context-delete is now triggered by provision-save with the --delete option

because they get initiated with empty root and uri values.

Conflicts:
	provision.environment.inc

the configuration based on the properties of their owner.

Get rid of the publish_path variable , which is replaced now by $this->root/d()->root;

work on some of the context stuff in provision_drupal.

the ability to redirect specific services to a different server.

also got verify working for servers and platforms, and started
the process of getting rid of drush_get_merged_options in config files.

Added a required context_type field which allowed us to get
rid of the environment factory guesswork.
