v0.4.2 of Mops & Mobs demo

During the AdventureX we received some feedback. The most pressing issue were errors happening during the combat card game, so we fixed those. Also included:

• changed dragging behaviour of enemy and dirt cards in combat
• added bounce-in effect in decoration mode
• increased size of Jelly's hitbox
• changed standing candle-holder to interactive

There's also a new door type, and a warning if the occlusion culling of a level is missing. The latter was an oversight happening quite often, so hopefully this will fix some performance regressions.

One big problem seems to be general instability and bad performance during the card game. We need some time to identify and fix those, so apologies for that.
