Fixes for Mines game

[Timothy J. Lipetz]

Thanks to the people who have written and posted comments on the
mines game port for the unix-pc.   I gather from the response that
a number of people are using the game.  (Don't you wonder how many
people actually use the things you post?)

Here are fixes for the two problems I have heard about.

FIX #1
Thanks to Bob Barbato for this fix.
The reason only some people got a missing cursor was because of an
unitialized member of a structure.  Here is the one line fix...

  	um.um_y = 0;
  	um.um_w = 1;
  	um.um_h = 1;
  	wsetmouse (wn, &um);

--- 171,175 -----
  	um.um_y = 0;
  	um.um_w = 1;
  	um.um_h = 1;
+ 	um.um_icon = 0;
  	wsetmouse (wn, &um);


FIX #2
Thanks to David Sandberg for the fix.
Some people got a messed up escape sequence going to the screen.
Here is the one line fix..

The original line in the source is:
 
        wputs(wn,"^[[2J^[[=1C");    

(those  ^[ were escapes)
and should be changed to
 
        wputs(wn,"\033[2J\033[=1C");
 


Hope this gets everyone up and running.
