Expose P_ResetCamera / camera->reset to Lua

As it says in the title. P_ResetCamera is useful if you're looking to reset the camera back to its default positioning, particularly after teleporting the player, while camera->reset will reset the camera's interpolation once !2008 (merged) gets merged. The former will also set the latter too.
