[Implemented] Read Database

Implemented as DatabaseColumIndex()

It would be nice to be able to use the column names when reading data from a column instead of the column number...

GetDatabaseString(0), GetDatabaseString(1), etc
becomes...
GetDatabaseString("Names"), GetDatabaseString("Address")

Using the current method, if a column gets inserted in between 0 and 1, the entire program has to be changed to accomodate the shift, whereas using names, the columns can still be found regardless of position.
