FILEMAN-85: Protect the application code from changes made by simple users
* Give explicit edit right to the Admin group for the application code space (FileManagerCode). You have to be an admin to install the application anyway.
* Remove the rights set on the FileManager (data) space (they were added when the application was initially created using App Within Minutes).
FILEMAN-86: Upgrade dependencies: AngularJS 1.2.27, Angular UI Bootstrap 0.12.0, JSTree 3.0.8
