Post-PR-3 bugfix & rebalance pass

Changes:
1) Fixes wireless AEGs being able to be recharged in conventional
rechargers. This prevents people with recharger access using them as
regular laserguns.
2) Fixes spiderlings from dying Mother of Terrors lingering around for a
long time. Now, they're forced to ventcrawl immediately if they can.
3) Improves queen health regen. She was regularly getting picked off by
one guy with a gun or two.
4) Queen and Mother now gain vent smash ability. Given how often the
crew welds literally every vent, this is necessary to avoid them being
totally shut out of the vent system in the late game.
5) Prince loses vent smash ability. Instead, he gets the ability to spin
thicker (vision-blocking) webs, and +10 melee damage.
6) Fixes 'evil looking spiderling' meta by requiring that queen has laid
at least 10 eggs before the ability is usable, so newbie queens
don't use it first thing and instantly get discovered/swarmed.
7) Adds confirmation prompt to queen nesting. Queens will no longer be
confused about why the cannot ventcrawl after nesting.
8) Reduces the chances of terror spiderlings skittering onto space
tiles. Makes them less likely to space themselves.
9) Tweaks TS event by increasing timer, and having one of the possible
infestation types spawn 4, rather than 3, green terrors.
