Merge pull request #3 from Thuleando/Shelley

Took parts of login procedure out into 2 triggers.
Added a second version of the Login project

Added Login_Authenticator2 so that we don't lose the work on the version
with the triggers. Moving forward with the current project, we can use
this second version.
Formatting
Added LockEvents, EventReasons, AccountTypes

Added tables LockEvents, EventReasons, AccountTypes. Changed Accounts
table to match. Changed procedures for login and account creation to
match the new structure. Also added bare bones of an unlock procedure.
Created a new .ddl file for this version. Created .ddl files for
initially populating necessary data, and for dropping all entities at
the end.
