[Freeciv-Dev] [Update] Happiness display (GTK client)

["Mike Jing" <miky40@xxxxxxxxxxx>]

These two patches add a Happiness display for the GTK client,
accessable through a new button in the City dialog.  I ended up copying a 
lot from the City dialog code.  Here is what the individual patch does:
new_city_info.diff:  modifies the city_info packet to included need
information to diaplay the happiness breakdown and adds a new optional 
capability string.
happy_display_gtk.diff: adds the Happiness display window.

NOTE: the displayed info will be *incorrect* when playing on unpatched 
servers.
More coming.  Please give it a read and test (thanks in advance, vasc. :-).

Mike
