zf-mvc-auth integration

- Currently pinning to feature/zf-mvc-auth branch of zf-apigility
- Enabled ZF\MvcAuth module in application
Add temporary repo for zf-mvc-auth
Updated dependencies

- Switched admin module to mvc-auth-integration branch
- Added repos for each of apigility and admin, to ensure composer can find the
  branches
- Removed example dep; proving to be a problem anyways.
Usability fixes

- Added zf-api-problem as a VCS repo so we can get the
  ApiProblemResponse on a base install.
- Added the AdapterAbstractServiceFactory to the Application module
  configuration to ensure db-connected works out-of-the-box.
Re-point deps at dev-master
Merge branch 'feature/mvc-auth-integration'

Adds zf-mvc-auth to the list of modules required.
