[PATCH] independent migrations

Description

this patch allows you to have multiple migrations with the same number, provided they have the same class (IndependentMigration). This enables branches to be merged without renumbering migration files, as well as local/remote mirroring with local DB enhancements. Simplicity was favored over features; if you get a conflict, you still have to edit the migration and comment stuff out and migrate up and down.

As a bonus a new metaphor in migrations is introduced, wherein two or more independent migration files can have the same number.

I just added timestamped_migrations.v1.patch, which is a work in progress. I documented it here here: http://blog.teksol.info/articles/2006/12/13/timestamped-migrations-status

Essentially, this patch replaces the version number with a UTC timestamp, and orders migrations by timestamp before running them. Each individual migration is recorded in a new schema_migrations table.

TODO: Test. Combine both versioned and timestamped migrations so that they can coexist. Test. When running db:migrate, run the versioned migrations first, then the timestamped ones. Test.

Okay, sorry. Don't take it like this. I just thought we should keep everything migration-related in the same place.
