Datafile: allLines() can return const reference instead of copy.

Browse source 
Not only does this eliminate the need to copy the stings to the caller, it will
also eliminate the need for any iterators over the entries in the Database from
having to hold a copy of the lines from the Datafile.

Related to #245.
