Enable rollback of all scripts from same migration

[ftreguer]

Hi, here is a possible implementation of migrate-mongo down command to enable rollback of several migration scripts of a same migration. When you process to migration you can rollback all migrations scripts from a same migration.

If you have 3 pending migartions and you run migrate-mongo up, migrate-mongo down --block command will rollback the three migration scripts.

It could be usefull if you want to integrate it.

Thank you :)

We should also update the README with the new -b --block option added to down command.

EDIT : sorry, actually there is no need to do that as there is the --help option
