added connect4 board
web client now displays a connec4 board with some functionality. Also, something seems to be preventing us from staging files within client-web/source with git add -A.
fixed travis issues
Added lcol_size and lrow_size which are the logical row/col sizes with the bottom left hand corner being [0,0]. Also decreased piece, and made the gameboard be the same size as an actual connect4 game.
