Refactored old tests to work with current implementation.

Also eliminated various std::string and QString::fromStdString

declarations from various files to get them to play nice.
Added tests for the database taking a person.

Currently, the insert method doesn't work, but too

tired to continue refactoring.

--Note:  Be wary changing the implementation in the

drcdb.cpp / drcdb.h file in the DRC_DB_TESTS; it is

directly connected to the implementation contained

within the main DRC project.
