android port: convert use of java.awt.Rectangle to own CityRect class

java.awt.Rectangle does not exist in the android SDK, so this patch
replaces its use within the Micropolis engine code with a custom class
with equivalent functionality.

This way all the classes in micropolisj.engine can be compiled with
the subset of the Java SDK that also exists in the Android SDK.
