Universal admin interface

We need an universal admin interface that allow to manage data stored on sites.

Features needed:
- Query/Modify/Delete ZeroTalk and ZeroBlog (and other sites) database without any source code modifications. (using only configuration files)
- Query/modify users limit using it
- [ ] Create sample configuration file for ZeroTalk and ZeroBlog (xml?, json?, js?, yaml?)
- [ ] Layout mockups
- [ ] ...Coding

This would be huge benefit for all ZeroNet sites, so it would be really nice if someone would be able to take this task, so I will be able to focus on core modifications.
