little patch for ordering in fixtures scenarios plugin

Maybe slightly off-topic, but I was watching debate about fixtures
order loading. I didn't like much the idea of deferring constraints
(DB engine dependency) but I really like Fixtures Scenarios plugin.
Wish this would get into the core some day.
So I patched it the way it is possible to name fixtures' files
similiar to migrations:

001_offices.yml, 002_departments.yml, 003_users.yml

The patch follows:
