delete, delete!, and delete_all will make the cache stale

[sideshowbandana]

What do you guys think is the best approach for handling this? How about one of these:

• do nothing, and tell developers that those operations are dangerous
• raise if someone were to try to call these methods
• alias delete to be destroy (but that goes against the docs that delete will just be a straight sql call)
• some hybrid where a developer can force the delete
• implement all of the above and let the developer pick :)

Since delete will just be a straight SQL call we should just document that calling delete will by-pass the cache and cause issues.
