The current code does not show a tooltip when word wrap is turned on and the text is taller than the cell height.

)

* feat(plugins): remove jQuery from ColumnPicker & GridMenu controls

* tests: use input checked property instead of attr checked

- this fixes warnings shown in Chrome and other browser console mentioning that we should consider using `passive` event listeners
- also uses a polyfill in case the `passive` option is not supported (for example IE)

- also remove `passive` mode to certain events that use preventDefault since that is not compatible with `passive` mode

* fix: found a few small issues while testing examples with jQuery CDN

- closes #667
- freezing columns cannot be wider than the actual grid canvas because when that happens, the viewport scroll becomes hidden behind the canvas... so let's throw an error advising the user to make adjustments

)

- when changing frozen rows via `setOptions`, it should recalculate each viewports (top/bottom)
- the previous code skipped scroll height recalculation and that caused the issue identified in #737

…method… (#765)

* Enable hidden property for column. Adds example-column-hidden, method getVisibleColumns() and alternate method updateColumns() calling event onBeforeUpdateColumns() for when a hidden property has changed but the column list itself has not changed.

* remove jQuery from example and add frozen rows/hidden cols example

* final changes: add frozen columns example, fix issue with hidden columns on frozen grid boundary, fix gridmenu control to work with .hidden flag on columns)

* changes as suggested in #765

* remove legacy treecolumns code - now unused

* fix typo and add back apparently unnecessary call to setcolumns() which does in fact do crucial refreshing of grid structure
