Instead of having a primary and a temporary layer, store the state of at most 32 layers in a bitfield. These can be individually turned on and off, and key lookup starts from the top, and goes downwards until the default layer to find a non-transparent key. This allows one to reuse a partially transparent layer: set the default, and the transparent parts will be reused. The numpad layer was updated accordingly. Having an interface to the layer switching things also makes it easier to build other behaviour on top of these. As part of the rework, layer handling was moved to a separate file, and into its own, full-blown handler. Furthermore, we now use a single bit for all keymap events.
