Ability to create Permission Schemas

/**
 * There can be different permission schemas, but only one will be active.
 * Active schema defines what groups are used to place users into when they are registered
 * or banned. Also, when Admin creates a new branch, he'll be provided with a list
 * of Permission Schemas which he can choose from. So when the branch is being created, 
 * the active Permission Schema will be chosen by default.
