can specify FooMigration as well as foo_migration
can specify FooMigration as well as foo_migration

previously, if you did this:

    rake db:new_migration name=foo_migration

your migration's class name was FooMigration, but if you did this:

    rake db:new_migration name=FooMigration

your migration's class name was Foomigration. simple fix.
