Implemented new mechanics to loot life cycle (durability).
When player touches (picks and drops) item, the durability of item will be extended, preventing quick despawn of collected loot.

Currently applied to:
- Coconut 10x
- Coconut empty shell 10x
- Bamboo rod long 10x
- Bamboo short 10x
- Driftwood 10x
- Stone 20x
- Obsidian 20x
The total durability depends on actual quality. Keep in mind that loots spawns in various quality.
Also items can be burned by fire or washed off on sea.
Also updated and added new animation handling structure. This will be not be visible now, but it is important to merge animations in future (like walking when crafting, or turning).
The current animations are really basic one. Also they do slide - this will be addressed in larger animation update. It is not efficient for me to do it now and completely rework it later.
Done fixes to reported issues.
Thank you for your growing support.
