Added more database table creation
refactored salt table and logic to allow for foreign keys
Added functions for creation of new list and deletion of list
Added method to get the listid given the username and listname
Can now add access to list for users who don't own the list
Merge branch 'database' of https://github.com/kingj3144/WebSys-KISS
added quantity (INT) to listitems table. Should it be VARCHAR for the units?
