Document any deprecated options now replaced by classes option

[jzaefferer]

Tooltip, dialog, what else?

[scottgonzalez]

Anything that's deprecated needs to be tracked in tickets. I can take care of tracking down the list, creating the tickets, and updating the docs.

Widget options that were deprecated:

• dialog: dialogClass
• droppable: activeClass, hoverClass
• tooltip: tooltipClass

[jzaefferer]

I'm going to update #257 to mark the deprecated options as such, using deprecated="1.12".

[jzaefferer]

Done. Scott created all the tickets.

Closing since the merge to the 1-12 branch won't autoclose...
