SidebarView does not dispatch hide and show events

[jasonsanjose]

At one point before df7a495, SidebarView would dispatch hide and show events.

Currently, it appears that clients would need to get a jQuery object for the #sidebar element and listen for panelExpanded and panelCollapsed.

I propose we either (a) update the documentation in SidebarView.js to match the current behavior or (b) we reintroduce the show and hide events.

Does this not work?

$("#sidebar").on("panelCollapsed", ...);
$("#sidebar").on("panelExpanded", ...);

That works, but the docs haven't been updated to reflect the change.

I'm working on this bug. Using solution (a) as it is the least invasive.

Confirmed fixed. Closing.
