[Freeciv-Dev] (PR#2773) Go To with estimated number of turns

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

This simple little patch does this.

I add lots of new sprite tags, with alternate forms that should give
reasonable behavior under current tilesets.

Note that if a goto path can be 1200 steps long you need lots and lots
of digits to show the # of turns.  On a 200x100 map even a reasonable
goto may need the hundreds digit.  Currently no tileset has a hundreds
or a thousands digit.
