Fix object leaks in database code

Browse Source 
Qt's database and query model requires that both the queries and the database
objects are out of scope before a database connection can safely be removed.

Solution: Properly encapsulate databases and queries in "{ }" and use a string
to cache the connection name for out-of-scope removal.
