Add catapult MPC and controller class

We want to shoot with the MPC, but we want to decelerate and reset with
a more traditional controller.  So, transition to the MPC, and back to a
profiled subsystem.

This makes some tweaks to the solver to get it to converge more
reliably.  There's apparently a scale factor which was scaling down the
cost matrices based on the initial p matrix, causing it to not solve
reliably...  Good fun.
