Style deletes keys from the hash on initialization

[angelic]

This causes problems so later instances of the same object aren't able to initialize with those keys. This affects :geometry, :format, and :processors.

Fix is here: angelic/paperclip@ec63aca937568005f0534fd6be90c051b8c316da Branch: http://github.com/angelic/paperclip/tree/issue_137

I was going mad trying to figure out why my :geometry was missing after reloading my classes (something very common on development).

I have defined my styles hash in a constant in a initializer, and I use it for several attachment models. After sending an attachment to one of them, the rest where not getting the :geometry value.

My external solution (not patching Paperclip, I mean) is to create a method that returns the literal hash, instead of a constant. It works for me without problems.

Correction: my alternative fix doesn't work in production.
