Changes

Hohmann transfer UX overhaul

Now has two main buttons at the top to switch modes:

When a Celestial is selected:

- Transfer (two-burn calculation)
- Flyby/Impact (one-burn calculation)

When a Vessel is selected:

- Rendezvous (two-burn calculation)
- Intercept (one-burn calculation)

If you are doing a Transfer to a Planet / Rendezvous with a Vessel you
have an option:

- Match orbit (this will set you up as a leader/chaser somewhere on the
  orbit rather than doing a Rendezvous)

If you are doing a Rendezvous/Transfer and aren't matching the
orbit you have the option:

- Arrival delay (secs) - so you can insert 10 secs behind your space
  station instead of on top of it, or use 1/2 the period of the Moon
  here.

If you are doing a Rendezvous to a Vessel or using match orbit or
arrival delay with a Celestial (so only if you aren't targeting a
Celestial exactly) you have an option:

- Create arrival node (this will add the second Maneuver Node for the
  Rendezvous)

And then there is the "Coplanar only" option which is now at the bottom,
for people to do a coplanar ejection, followed by a MCC to intercept for
a lower total cost.
