Slot function to receive the pressed_but_nonselect signal

get into this function
This function implement these things:
1.Before clicking this cell, if you have already clicked(selected) a
colored cell, then this function detect whether there is a valid
path from the selected loc (self.selected_loc) to this loc(x,y).
If success then move the colored cell to this loc and then set the
previous selected_loc to blank(valid), else only set the previous
selected_loc to valid(only view this action as canceling the seleted cell)
2. If there is no cell seleted before do nothing
