For History/Favorites it replaces the MenuButton, which duplicated
a lot of functionality in HoverMenuButton.

I didn't know that an additional event options object gets passed
to each event handler.

Now we have all our dependencies loaded dynamically.

HoverMenu is now used by both MenuButton (Favorites, History) and
HoverMenuButton (cfg, property, ...).

Moved HoverMenu from Docs.view.tree to Docs.view namespace.

The menu can be configured to:

- show columns.
- show "x" buttons after links.

Now this expand/collapse logic is encapsulated inside the tree and
when class is clicked it fires classclick event which we can handle
in the controller.

Now when favorite removed by clicking "x" in dropdown menu, the
star icon will also disappear from the class node in tree.

Instead of listing all the view classes in Controller, define inside
MenuButton that it depends on HoverMenu.

This contains the shared functionality of History and Favorites,
which both use localStorage.

Otherwise we will find "Ext" from store that only contains "Ext.Array".

Removed index_production.html - it goes too easily out of sync.
Instead using index.html as a template where placeholders are
replaced with data optionally passed from command line.  For that
added new options:

  --title - to set the title of page.
  --extjs-path - to use extjs/ext-all.js in production.
  --append-html - to add the analytics code.

Quick and dirty copy/paste implementation based on History.

Needs to be refactored and cleaned up.

- Syncing store with localstorage when deleting items.
- Initial load is now done inside Docs.History.init.

Currently setting the limit to 25.

Now also keeping the store in reverse chronological order, inserting
items at the top and removing items from the bottom.

Fix adding items to history by setting correct itemSelector for
HistoryItems view.  Wrong selector caused crash when menu had
been already rendered.

Easier to type.

The public/private status of several classes changed in SDK.

Make Class#lookup return nil if class not found.

From now on, running JSDuck on ExtJS 4.0.1 will generate a bunch of
warnings as some classes that should not be private are marked as
such in ExtJS source code.

Use the --private-classes option to turn showing of private classes
back on again.

Just like subclasses, currently even using the same icon, because
I don't know of any better.

Hide inherited checkbox now also hides items in menus and changes
the member-counts to reflect the change.

Detecting the version and description of @deprecated tag.  Showing
a red warning in deprecated methods.

When {@link Foo} found and Foo is alternate classname for Bar, then
link to Bar is created instead.

Currently at top of the class hierarchy.  Maybe there's a better place,
but it should do for now.

All widget.* aliases are now recorded as xtype names.

Although currently SDK docs still only display one xtype per component,
because @xtype overrides any xtypes detected from code.  (It's the same
with alternateClassNames and mixins.)

Class config now has "xtypes" property which is always array.

Currently it throws errors.

- No tabs, spaces.
- In scss file using the same style of brace-placement.
