Update 14 - Arrows and Selection Preview

In the last update (which didn't had a dev log) I updated the event system and the sheeps. 
The sheep will not move on a tile anymore where a character is. 

Events get now triggered by turns and the needed turns are displayed with a number beneath the event. Currently the only event are the sheep. But I refactored the system so I can finally start to add more events like the bees I'm planning since some time. 

In this big update I added some arrows between the tiles you plan to match so it's much more readable what will happen. In addition the selected tiles that will get merged get some transparency. As many people reached out that they want to see the upgrades, we added a preview what will be build at the destination cell. 

I'm not 100% sure if this is the right way, but hope to see some playtests. If you have feedback, do not hesitate to reach out.

Happy tree matching!
