Zehlar v0.6.6

This update was heavily focused on improving the mesh generations systems performance and code simplicity. 

New

• Wooden stick can be obtained by cutting a tree branch or a wooden plank with an axe.

Improved

• Network Terrain Messages receiver was doing unnecessary copying of the terrain data, wasting processing time.

Changed

• Chunks chunks now have no mesh of their own. But rather a list of meshes. This was made to keep the same workflow for all the possible meshes inside a chunk (Solid terrain, Fluids, etc.).
• Unified all mesh systems in a single system (Mesh generation, collider and render). This eliminates the need for copying the mesh data multiple times, and the need to store that mesh data somwhere to be used by all the systems, decreasing memory usage.
• Potions can be consumed when the player is full.

Fixed

• Player blocking mouse pointer when trying to place a crafting scheme. Making it impossible to craft in 1st person view.
• Player could change selected ability while executing a continuous ability (like using the glider), causing unexpected behavior.
