Usage of uint

[exectails]

Hi there. I was wondering what the reasoning for using unsigned integers was and whether you've considered using signed integers instead. While uints communicate well what the intended or possible values of a variable are, it's a somewhat unusual type to see in C#, where signed ints and longs are usually preferred. When integrating DotTiled with other C# libraries in particular, you have to cast a lot, which can be a bit bothersome. As such, I would suggest changing the types. What do you think?
