Sleeping tweaks, at-will wakes (#21452)

Species capable of indefinite sleep can now wake up from being asleep at
will by pressing "Sleep" again.

IPCs will also no longer beep constantly when sleeping. This is part of
a `snores` variable that can be toggled on other species too in lieu of
a `snore_key` variable.

Unfortunately does not make IPCs stop consuming charge when asleep.
Tried it, it's one hell of a spaghetticode nightmare for a result that
really doesn't matter that much. Might revisit once the IPC rework gets
merged.
