[PATCH] Hackalicious STI support

[Xavier Shay]

Just enough to get this to work on rails 2.0.2

Old behaviour:
Clone::Work.find(:all) # select * from works where type = 'work'

New behaviour
Clone::Work.find(:all) # select * from works

I make no promises about either its correctness or function, but it
Works For Me

Also there is a test yay
