Sheet: provide access to row value during rowSelect and cellSelect events

[VsevolodGolovanov]

Describe the feature you would like to see added

Like e.g. p:dataTable puts rowData into its SelectEvent and UnselectEvent.

Is your feature request related to a problem?

E.g. for when there are additional UI controls being rendered outside the sheet, but in the context of its selection.

Describe the solution you'd like

New event classes providing additional sheet specific info. But it could also be new methods on the Sheet class itself.

Describe alternatives you've considered

Actually Sheet#getRowNumber(Object rowData) would be helpful too - for interacting with Handsontable API in terms of row numbers.

Any interest in helping with this one? We use the sheet heavily in a couple of production apps and I haven't found the need for this yet but I do absolutely see the value!

It looks like the sheet_selection is in the AJAX request would just need to parsed out and added to the SheetEvent
