GridBox (Done) and Adjustments

the main coding to get the grid box to display arrows on touch is finally working and done, need to add removing a line if it is wrong.  Also updated .gitignore to allow the launcher image to save with Git as well

for future reference, recording data from the lines in GridBox should be as follows
int[] of 9 ints,
for each start point of a line in a box, the corresponding integer gets +1, for each end point of a line in a box, the corresponding integer gets +2, else 0
this creates the following system
0 = nothing, 1 = pass, 2 = receive, 3 = receive then pass
using this system, a general sense of the lines can be re-created after leaving the match, and assist scoring can be calculated
