Extracting a big chunk from the god class JsDuck::App.
The options object can now be easily passed around, unlike
with the previous system where every option needed to be
passed separately.

The bin/jsduck is now really short and readable.

'options' is a common name that one could give to normal event param,
better to have this special appended param named so that there's
smaller chance for conflicts.

Bit of refactoring.  Using the each_member method of JsDuck::Class
and also adding local each_member to loop over members of all classes,
plus a local warn method to more easily format warnings.

Previously it was required that (optional) is always lowercase.

With this we avoid creating a link every time some text mentions
Ext JS. But we still get a link when Ext.SomeClass is mentioned,
or even if Ext#get is mentioned.

Instead of the previous 'void'.

Also hide the return type in method signature if method returns nothing.

Even if parent class is not included to documentation, it still
makes sense to mention that a class has a parent.

We still print warning if a parent is missing, though.

Mistakenly pushed half-finished gem to RubyGems.
Deleted it from there, but RubyGems doesn't allow pushing a
previously pushed version up again.

Although singleton classes shouldn't have its members marked as
static, excluding them completely from the docs isn't the right thing to
do.

For example the checkbox image was missing when viewing the
released-jsduck-generated docs app.

Keeps the Favorites controller cleaner.

Moved most of the logic that binds together Docs.Favorites,
FavoritesPanel, and Tree into this controller.

Also moved the drag-drop logic from FavoritesPanel to ClassGrid.
Looks like a better place for it, and I can also fire the needed
events (for controller) more easily directly from ClassGrid.

No more add the default top10 favorites, leave the favorites empty if
it's empty.  Automatically show the favorites panel when first item
marked as favorite.

Moved the tabpanel with favorites to separate class.

The Docs.Favorites is now observable, firering "add" and "remove" events
which are listened both by the tree and the grid.  The Docs.Favorites no
more knows anything about the tree.

No need to pretty-print these, as they are syntax-highlighted
by the CodeMirror library.

The actual previews are now only loaded after the preview button is
clicked.

The loading time of Ext.button.Button on my local machine dropped from
~4.4 seconds to 1.8 seconds.  That's about twice as fast, although
overall it's still a bit slow.

This comment will be removed anyway in the final compressed app.js.

Although most of the JavaScript was already compressed, apply
YUI compressor once more, to compact the uncompressed parts too -
most notably the CodeMirror source.

Use a hackish way to locate yui-compressor relative to sencha command.

I'd like to include the compressed version also to release version
of JSDuck - these files have to be referenced separately then.

Also excluded the localStorageDb name config - similar case.

The Docs App JavaScript file now gets build with minimal amount
of ExtJS in it.  Added a missing dependancy to app.js to make it
work.

Use ext-all-debug.js and ext-all.css for inline examples.
This way the examples use the standard ExtJS styles and
are also debuggable.

Now all the libs are located there.

Implementing full copy-to-clipboard turned out to be way too much
trouble.

The placeholder for ExtJS path had been lost from index.html.

Using the sencha SDK tools.
