Created `user_descriptions` table

Finally, some database normal form up in here!
Added `user_descriptions` results to getUserInfo

dbUserEditDescription, publicUserEditDescription

Added user_descriptions to dbUsersGet
Finished backend user description functions

publicUserEditDescription changes session

This will help with the front end. It's also commented now.
Account page has entry for user descriptions.
