Craftica Update: : Various Improvements and Fixings

This update has added a minor improvement to physics simulation that could reduce agents (player's character, villagers, animals and mobs) bouncing away when collided improperly with the terrain or objects. It also added a few other minor improvements for human striking animation and flying posture, and agent spawning. It also improved the handling of mining on combo blocks (block composed of two materials).

This update also fixed various issues. It fixed a recent handling of vertices in mesh building that cancels mesh optimization, and some minor issues in:

• Tree or forest generation: inconsistent generation near octant borders;

• Locating a neighboring section: preventing item placement at certain locations;

• Locating a block in a neighboring section: same as above;

• World sections in terrain updates: causing some objects not showing up;
