Take planets by killing what defends them

#211 conquest is the fight now: a planet registers the garrison its setup
authors, each defender's own death counts against it, and the last one takes
the world. The capture points - stand in a ring, wait out a timer, once per
ring - are gone, along with the editor palette that placed them.
#212 conquest opens a dialog on the surface naming the research points
recovered; the award travels with the signal, after it is banked.
#209 the prologue's charted sectors go with the breach, so the map the
survivors keep is of where they now are - and "chart 30 sectors" is no
longer complete before they have flown anywhere.
#218 enemy variety is gated on the FLEET, not on wave strength: a starting
fleet meets chasers only at any wave number, and each vessel past three
opens one more kind.
