commit 35a47705f93f3102f3560afd630d2b41c29d4fd8

    4253: Let Workbench Manage Account partials render their whole pane.
    
    I'm about to add another "Add" button to the Repositories pane, so I'd
    rather do it this way than try to maintain a generic loop inside
    _manage_account.html.erb.

commit 39b482948ad34c268658597bad9e6ace73f0dd91
Author: Brett Smith <brett at curoverse.com>
Date:   Mon Mar 30 11:06:51 2015 -0400

    4253: Sync up Docker with our production Gitolite setup.
    
    This updates our API server Docker image to store repositories by
    UUID, with name aliases available.  .gitolite.rc enables the aliasing,
    and update-gitolite.rb generates the necessary configuration.  This
    makes it possible to test the recent repository changes in Docker.

commit fd3278f525ea0afa54d3eef8c9705f9b44d629af
Author: Brett Smith <brett at curoverse.com>
Date:   Tue Mar 31 09:23:56 2015 -0400

    4253: Users can manage their own repositories.
    
    This commit allows users to create their own repositories, as long as
    the repository name starts with their own username.
    
    To support this change, we've modified our Gitolite setup to store
    repositories primarily by UUID, with a name alias for easier
    checkout.  fetch_url and push_url become generated attributes
    accordingly.  This makes it easier to rename the repository later and
    allow checkouts to continue to work.
    
    Commit includes contributions from Tom Clegg.
