Simplify database selection

Do not require every script that sources stackrc to also
source lib/databases.

* Move use_databases() to functions
* Set DATABASE_TYPE in stackrc
* Allow setting DATABASE_TYPE in localrc to work
  (use_database() essentially just sets DATABASE_TYPE at this stage
  so continuing to use it is equivalent)
* Validate DATABASE_TYPE in stack.sh.
* Change sudo to postgresql user to go through root to eliminate
  password prompt
* fix use_database error condition
