• add minRow and row grid options (which set minRow=maxRow=N) 1172 - thanks @RadoiAndrei
• fix 1166 resize not taking margin height into account - thanks @awjae
• fix 1155 maxRow now limit initial item placement if out of bound, preventing broken drag behavior
• fix 1171 added event support to call grid.on('added removed change', callback) again even with native events.
