Created GuideAchors class which transforms the hashes in links
and ID-s in anchors so they don't interfere with Docs app #!-navigation.

Relaxed the pattern matching of guide URL-s in Docs app and added
support for navigating to <a name="..."> anchors.

For classes we now always show the short name in tab title and full
name in tooltip.

For guides/videos/examples the title and tooltip are the same, with
tooltip providing a way to see the title when it's too long to fit
on the tab.

We're going to use #shortName also inside Tabs class and want to
share the code. #packageName is a related function and should be
together with #shortName.

Previously it depended on whether you viewed classes by package or
by inheritance.

Mike fixed the server side escaping, so we don't need this hack any more.

Only activate the external guides-search when --search-url option
is used.  Otherwise fall back to old search.

Initial version of the UI - the search results are combined with
API search and shown in the same old dropdown.  This means there
isn't quite enough room to show the full context of full text search
matches and the search is also slower, but it fits nicely to the
current UI.  Plus it was easy to implement.

The most questionable part is how the guide results are placed inside
API search results.  I'm drawing some arbitrary lines between the
scores given by guides search to split the results into boxes like
the API search does.

The problem arose from links produced by Marketo which took the
following form:

    http://docs.sencha.com/architect/2-0/?mkt_tok=LONGHASH#!/guide

Now we're stripping all URL parameters after the question mark, leaving
just the path and hash-bang parameters.

Previously the order was pretty-much random.

Leave just small stars behind new classes.  This way it's lot
less cluttered.

The new "New in this version" section covers the details of
what's new much better and doesn't get on the way.

Instead of having the class names in headers be the links.

Use the Columns class to do the splitting in exactly the same way
as in Categories.

Let it manage the columns splitting logic so we can also share it
with new items list.

Vimeo now provides an iframe.  The good part is that within this
they do their own Flash detection and say to you when you are
missing Adobe Flash.

Also less code, althogh it's an iframe.

As suggested by Meg.

Forces exiting with code 2 when warnings present.

Fixes: #347

To force terminal colors on/off.

Fixes: #348

Temporarily patch the Ext.dom.Element#getAttribute method.

To easily insert current data and link to JSDuck homepage.

Fixes: #343

This is to allow third-party packaging of JSDuck without the
inconvenient dependency on therubyracer gem.

Fixes: #339

Check if jsduck.json exists in current working dir, if yes, then
read configuration from it.

Fixes: #335

Looks better IMHO.

In the case of Touch examples, the separator is no more needed
in this case.

Simply copy over the toolbar code from Touch example component
and generalize the handler for the button.
