v0.0.20: The long game

Every player now earns Rime Essence when each day ends, and wisps pay out fairly in groups - progression is much faster, especially in co-op
Skill tree revamp: more levels, new early nodes, new advanced classes (Quartermaster, Stormcaller, Frostcaller), and locked nodes now show exactly what they need
New building: the Stone Door - a wall piece you can open and close; enemies path through it only while it is open
Skip the day: start the next wave early (instant solo, team vote in multiplayer)
Respawn at the Base with a countdown, and PLAY AGAIN on the results screen for the whole party
Base upgrades can be paid in over several trips, and teammates can chip in; anyone can upgrade a teammate's tower
Power is easier to learn: feed towers by holding F, or order it from the commander view
Hold the Hollow (Endless) gets brutal after wave 10, and The Deep is now as tough as surface Insane
Fixes: shop buttons, Esc closes shop screens, menu flicker, guns held properly in third person, RTS mining spots, Jack of All Trades, prices with discounts, resource sync in big games
