Description

Rails migrations have a nice feature called "scope" (as described here: http://edgeguides.rubyonrails.org/engines.html#engine-setup).
This feature enables running only migrations that belong to a certain scope.
I propose using this feature in our plugins to mark plugin's migrations, so we will be able to migrate up or down only those migrations. Effectively it will enable us to uninstall every table that belonged to a plugin.

In order to use scopes, migrations should be named accordingly: [timestamp]_[migration_name].[scope].rb (the change is adding the ".scope" to filename).

Once all the migrations are named that way, we can migrate them up or down using:

# set up a plugin:
rake db:migrate SCOPE=my_plugin

# remove the plugin from DB:
rake db:migrate SCOPE=my_plugin VERSION=0
