Demo - Patch 0.1.2

[p]Hi all,[/p][p][/p][p]yesterday I updated the demo to add a new building: the bridge.[/p][p][/p][p]This patch is to fix some bugs regarding the bridge and also the framerate for the numbers.[/p][p][/p][p]Additionally I added a beta feature for automatic placing a bridge when you cross two conveyor belt paths, so no need to place it manually.[/p][p][/p][p]Both, the bridge and the auto-bridge feature are still under test so if you find any issue with them please let me know.[/p][p][/p][p]Thank you again for your support.[/p]
