wip

Update README.md (added video and updated replay link)

Added system to make large objects transparent when characters walk behind them (e.g. tops of trees)

Fixed missing activity stream entry for failed craft item action

First pass at integrating fog-of-war system with agents

Requesting a path to a blocked cell now searches for a open cell nearest to the path start point

Fixed incoming webscoket message handling accessing calling simulation from the websocket's background thread instead of the simulation thread

Fixed long press gesture activating after moving pointer

Fog-of-war is now fully server authoritative.

Removed all English strings and icon URLs from activity stream entries, replacing them with entity IDs and item config keys.

Implemented a concept of "collision flags" and used Walking vs. Placement flags to re-implement farm plot placement rules using the collision map. Next step is to reproduce the collision map on the client for client-side predictive feedback of placement success/failure.

Added "Support for multiple regions within a simulation" to README "Areas to develop"

Auto-interaction now filters down to selected entity if one is selected

Add hold to click to emulate desktop right-click behavior, especially for mobile input

More client code re-organization, clarifying React UI "components" vs. simulation entity components, better separating engine, common, and game code
