Refine groups functionality

Every project is in group "default".  "-default" does not remove
it from this project.  All group names specified in the manifest
are positive names as opposed to a mix of negative and positive.

Specified groups are resolved in order.  If init is supplied with
--groups="group1,-group2", the following describes the project
selection when syncing:

  * all projects in "group1" will be added, and
  * all projects in "group2" will be removed.
