Extend Security Provider with Permissions from Database

[JonL]

Removed my vote because Dynamic Bindings make more sense as it allows more flexibility.

Dynamic bindings in conditions of Permissions

Similar but I think that using SC bindings makes more sense. Right now we have a hard-coded permission system. Implementing a database hardcoded approach would just extend a tiny bit the options. What if I want to store my permissions on a file? Or what if I want to implement a custom module that spits my permissions. All in all, I think bindings(which cover DBs) make more sense and results in a more Wapplery way.
