[FreeCiv-Java] City Report Dialog

[James R <bullwinkle@xxxxxxxxxx>]

Hello, I've implemented the City Report dialog.  It isn't working currently (it 
displays some static data instead of real data), but it does contain all the 
components correctly.

I'm currently using code from the tutorials from java.sun.com (to sort the 
table).  I'm not sure about the licensing with this code, and if it is 
necissary I can write my own algorithem and code to sort the table.

The other dialogs should be fairly easy after this one.
