admin: Separate base projects from user projects

Separate the default base projects that every user has, from the
projects that users can create on Synnefo. Name the former "Base
quotas", since these projects are essentially the quotas that users
start with.

Fix apyrgio/synnefo#63
admin: Add resource sum and comments for project

Add the following in project list:
* Resource summary for the resources that are granted to project as a
  total.
* Resource summary for the resources that are granted each member of a
  project.
* Comments for review, if the user has added any. If the application is
  accepted, the comments for review should remain since they may be of
  use later on.

This should address the second task of apyrgio/synnefo#64
