Changes due to 3/18/14 phone discussion

On login, project asks for keys the first time with username and
password for the database. If successful, keys are saved so that the
next login does not require the keys.

Adding information was done differently to handle only one database.
Class and parameter adding was also done differently. Bugs with the
“AddDatabase” window were fixed.

Coding restructured to suit changes. Back to the point the project was
at before changes to how login and the data would be handled.
