0.3.3 - bugfix, balance

- fixed animations when depleting milk from a breast

-  minor balances to upgrades

- refill no longer pauses if the shop is displayed so you can refill while buying upgrades (also, you can press Z  on keyboard to toggle shop)

- also shortened the time it takes to start refilling from 5 seconds to 3 seconds  (and still once both breasts = 50%)
