Trebuchet: fix icons disappearing from the hotseat (dock).

The "occupied" array for the hotseat should be [numHotseatIcons][1], not
[numColumns+1][numRows+1], because numHotseatIcons can be >1 more than
numColumns; so the rightmost hotseat icon is lost on restart if, for
example, the workspace is 5x5 but there are 7 hotseat icons.
