Updates the model used to store and retreive permissions, instead of a single string it is an Enumerable<string> which gives us some flexibility in the future and since this was not public (yet) it's the perfect time to do this.
Removes the base Profile classes from User since these are not required, since we cannot share base classes between Member and User, these weren't necessary.
kept all properties, etc.. internal just so that they can be found so we don't have to register them.
Updates unit test to ensure the plugin manager is init'd properly with the 'false' override. Ensures that the base
db test also initializes the plugin manager properly.
Moved getting an IProfile to an extension method, as its not commonly used.
Removing dependencies in ContentService, so the Services and context can be moved to Core proj.
Implementing Template repository to use both filesystem and db.
Adding a UserService, which should be fully implemented in a later release.
Refactoring usage of the ServiceContext, which is now loosely tied to the HttpContext as its used by the UserService.
Refactoring User/Writer on the Content class and interface.
Simplifying events and delegates in the publishing strategy.
