Rollback changes to the removal of Projection Hack support

[Ralyks]

Projection hack is vital to the Dof Hack for skyward sword, i would like to see support added again for it.

While it's true that the Skyward Sword DoF hack that is commonly available right now relies on a projection hack, that doesn't mean that a projection hack is needed for Skyward Sword DoF hacks in general. It would be possible to create e.g. a Gecko code that does the same thing (or that does it even better, removing bugs with things like timeshift stones), so I don't think keeping the projection hack feature in Dolphin is worth it just for one possible way of implementing one hack in one game.

Keep in mind that projection hacks are rather hacky after all, and the DoF removal projection hack does break some important things in Skyward Sword. We would rather not keep such a badly working feature around, on top of the limited usefulness it has.
