[Freeciv-Dev] Revised Trade units patch

[Kris Bubendorfer <Kris.Bubendorfer@xxxxxxxxxxxxx>]

Well, playing with the trade units patch showed that better identification of 
the units in question is needed, plus a couple of bug fixes and all the other 
stuff in the previous version as well.  This patch applies to the current CVS 
and not to previously applied trade units patches.

1. If you trade one unit out of a stack, then this is now resolved.

2. When a unit is added as a treaty clause, the map is centered on the unit's 
position and a red box is temporarily drawn around the unit (until the next 
map refresh).

If this was not the intended position, simply delete the clause and as the 
terrain is no longer revealed to the other player unless the unit is actually 
transferred - there is no security breach.

3. Once the treaty is accepted or cancelled, the map returns to it's original 
(pre meeting) coordinates.

Try it out please, and if this is liked - I can add the centering and the box  
to the trade cities selection as well.
