Title: Heading-hold flight mode

For #450.

To activate, hold control and click the flight mode switch on the dash to cycle it round to "Heading Lock (fore)" or "Heading Lock (aft)". In this mode, the autopilot controls your angular thrusters, leaving the linear thrusters free for manual burns. This makes it easier to (for example) decrease your orbital energy by burning directly along your orbital path.
