v4.0.0

• fix #149 #1094 #1605 #1534 re-write of the collision code - fixing 6 years old most requested request

1. you can now swap items of the same size (vertical/horizontal) when grid is full, and is the default in float:false (top gravity) as it feels more natural. Could add Alt key for swap vs push behavior later.
2. Dragging up and down now behave the same (used to require push WAY down past to swap/append). Also much more efficient collision code.
3. handle mid point of dragged over items (>50%) rather than just a new row/column and check for the most covered item when multiple collide.

• fix #393 #1612 #1578 re-write of the drag in/out code - fixing 5 years old bug

1. we now remove item when cursor leaves (acceptWidgets case using dropout event) or shape is outside (re-using same method) and re-insert on cursor enter (since we only get dropover event). Should not be possible to have 2 placeholders which confuses the grids.
2. major re-write and cleanup of the drag in/out. Vars have been renamed and fully documented as I couldn't understand the legacy buggy code.
3. removed any over trash delay feedback as I don't see the point and could introduce race conditions.

• fix 1617 FireFox DOM order issue. Thanks @marcel-necker
• fix changing column # column(n) now resizes cellHeight:'auto' to keep square
• add 1616 drag | resize events while dragging. Thanks @MrCorba
• add 1637 GridStack.setupDragIn() so user can update external draggable after the grid has been created

v3.3.0

• big re-write on how cellHeight() works. you can now call it at any time (not just grid init options) including switching to 'auto' or other modes on the fly.
• fix cellHeight:auto now keeps cell square as window resizes (regressing from 2.x TS conversion). Utils.throttle() works better too (guaranteed to be called last event)
• new cellHeight:initial which makes the cell squares initially, but doesn't change as windows resizes (better performance)
• new grid option cellHeightThrottle (100ms) to control throttle of auto sizing triggers
• fix 1600 height too small with cellHeight:auto loading in 1 column. Now detect we load at 1 column and size accordingly (default 'auto' could make big 700x700 cells, so explicit px might still be wanted)
• fix 1538 loading nested into small size and sizing back up
• fix 1604 nested grid resizing fix
• fix 1599 H5 resize from left side can move item right
