City Data charts and Map markers

Took some time to play Elden Ring DLC and then had a break from game dev in general but now I'm back!

What's new

This time I added new data classes to cities to gather data about resources stored, produced and consumed as well as population. This information then can be seen in statistics tab of each city. This sould help players make a better decision of what each city needs and makes

Other feature I'm adding is Map Markers. Just press right mouse button enywhere on map and Marker menu will pop up. Select marker icon and solor and place it on map. With this I hope players will be able to make the map more informative by letting players place markers around cities to indicate what resources they produce or need according to player needs

What's next?

While data chart is cool addition it should be improved with adding a chart what lets see player own stock in each city. Also might need to create new UI specificly for player statics across all cities.

And I sould also work on some AI players adding more life to this world and some competition to you!
