Power-Mode save states - Keybind compat

[leafreynolds]

There's tons of powers in the mod suite and it can be very annoying to need to turn multiple on/off.

As a player, it would be convenient to push one keybind and have it save all the modes each power is set to. Then later, be able to push a different keybind and have it set all powers to those modes.

Additionally, it would be nice to roll this into the UI updates we would also like to do. This could mean selectively setting only a few powers to specific modes, rather than every power.

I had an idea for this utilizing a command. A player could use the following commands to add or remove powers to a mass activator. "/cosmere activator [#] add [power type] [level]" or "/cosmere activator [#] remove [power type]," where [#] is the mass activator number (1-4), and the other two are pretty self-explanatory.

I can get started on making the activators even if you don't want the command-based implementation.
