Merging DBD::RAM into DBI

Hi all,

I'd like to merge DBD::RAM into DBI for several reasons:

1) It's a tiny one without much dependencies, it should run fine
    with just DBI::Sql::Nano (or should)

2) I had an evil idea how to allow Pure-Perl drivers can work
    together in one instance like:

      DBI->connect( "dbi:DBM:", , , {
        sql_join_drv => "DBD::RAM", ... } );

    But there is something for testing required ;)

3) It currently doesn't get some love, even if it should get.

Any comments?

Cheers
