By doing the selection after expand, the tree scrolls the selected
item to view.

This way all the methods are named similarly:

- loadClass
- loadGuide
- loadIndex

The activeUrl was not set when switching to index page, so when
one tried to switch back to the previously visited page, that
page was still listed in activeUrl, and the switching was cancelled.

Now all pages are switched through the Classes controller.

Well... before this there was no error message at all - just
the load mask stayed on.

Convert favorites saved in old format to new format.

Make history and favorites work with guides.

Lots and lots of refactorings.

This allows us to specify a particular order for the guides listing.
Additionally: the guides not listed will be excluded completely.

JSDuck creates HTML for the guides section, listing all the
available guides specified with --guides option, and places
the HTML in index.html inside a hidden div.

Tweaked styles to automatically adjust to fit all the guides links
to the Guides section at index page.  Previously the column-widths
were simply hard-coded.

Additionally the guides section will now be completely turned off
when no --guides option specified.

Store each icon alongside the guide itself in SDK.

For guides without an icon, use the default icon: guide-icon.png

Moved test for xtype-begins-with after name-full-match.
The same way they are ordered in results.

For example when searching for "store" the beginning of the search
results list contained a lot of "store" config options and the
"Store" classes were furthere below.

Now the classes are always before members of similar match category.

It was rendered as a button before.

The toolbar now just fires events + performs the filtering of
dropdown menus in toolbar.

Actually for any singleton just say it has no static members,
but if there are static members defined, print warning.

Instead of preventing the selection from happening at the first place,
which conflicted with drag-drop, allow the selection to happen, but
after the fact re-select the currently selected item.

Favorites and Settings are force-loaded before viewport is created,
so they can be used right away in all views.

Also set up resize listener in listeners config, not in afterrender.
