Allow for override based on db type

[byrnedo]

Would it be possible to read files from a dir, say ./sql, but if the driver is sqlite3 and there exists the same number revision in ./sql/sqlite3/, that one is run instead of the base migration?

That's currently not supported, but that might be useful to add. I think this could be implemented without including the new directory, for example:

• base migration: 001_create_tables_up.sql
• sqlite migration: 001_create_tables_up_sqlite.sql
• postgres migration: 001_create_tables_up_pg.sql
• ...

How does that sound, @byrnedo?

[byrnedo]

Yeah that could work. Would be a bit more transparent too.
