- Deployment list now has optional "details" parameter. If "true", all deployment detail will be included in output.
- More logging for gitdeploy (de-)initialization.
- Fixes for JSON patch support.

- All endpoints now support JSON Patch documents (RFC 6902) for the PATCH verb. This is the only way to (for example)
remove nested object keys. See docs for details.
- Added username of triggering user to Deployment object (GET /app/{appname}/deployment/{deployment_id})
- Internal data layer reorganization, bug fixes

- Fix authentication for application container endpoint (GET /app):
* GET - application list will only show applications for which user has at least read permission
* DELETE - request will succeed iff user has write permission for the requested application
* PUT - request will succeed iff user has '_global' write permission (admin privileges, essentially)
* (previously user required '_global' permissions for all verbs)

- Fix computed user permissions endpoint (applications was blank) (GET /global/users/{username}/permissions)
- Fix gitdeploy endpoint exception (GET /app/{appname}/gitdeploys/{gitdeploy_name})

- Don't allow users to change their own permissions

- Fix ability for admin or other user with admin permissions to view user object endpoints (GET /global/users/{username})
- Change output format of user endpoint to be consistent with other objects (JSON response has top-level "user" key instead of "message")
