Role Viewer and Group Viewer

[ShawnClake]

Add a backend interface for managing a single role or single group. This is an extension of the Role Manager as it gives a complete view of something more specific.

• Extended Role/Group information
• Large list for users in Role/Group
• Statistics
• Manage Role/Group avatar image
• Group/Role image gallery. Usecase: If a group is 'Tour Guides' they want an image gallery of what their role has done previously. The group image gallery is a culmination of all the Role image galleries.
• Manage permission nodes included in the Role/Group. A group permission node is inherited by each Role.
• Add a toggle switch for inheriting permission nodes from roles below this role
• Add a switch/checkbox for enabling 'Wildcard' for the selected permission node
