accounts work

user profile page now has an admin panel attached, only viewable by
admins.
Sessions will now detect user_level and redirect appropriately.
Accounts model now has an array of account types.
User/show will now show all associated accounts.
All account functions have been admin limited except for show.
Did some work on Account new and create, but it's going to be erased for
a new/easier way.
fixed git merges
