[Freeciv-Dev] (PR#13622) Easier city rename

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

I like the interface.  However it's got a critical flaw in that it gets
into infinite loops.

If I type in "Hello world" it gets stuck on the He.  Because it updates
the name for each character typed I think it sends He to the server. 
The server discards this becuase it's an invalid name (for some reason).
 When the client receives this packet it tries to send the name again.

A related issue is that even if things work typing would be slow.  After
you type each character a round-trip to the server is needed and then
some client drawing must be done.  The update should only be done after
you click "off" of the edit area (much like changing a file name in a
file browser).
