When type definition names a known class, it's converted to link
into that class.

Add CSS files to touch rake task.

It's not fully correct, but at least it makes the @member tag work as expected.

Also some refactoring of the other rake tasks.  live_docs task is now
renamed to live_sdk.

The --title now specifies both the <title> and the contents of the header
at the very top of docs app.  The new default is "Sencha Docs - Ext JS".

The title is no more used in classes index page.  This has now static heading
"API Documentation".  Also the guides, videos, examples index pages have
headings without "Ext JS" in them - so the headings will work also for
Touch and whatever else.

Finally the title is also used in print version.  For this did some
refactoring with writing the template files in app.rb.

Makes it possible to say "Ext.data.*" in categories file and have
all the classes included automatically, instead of listing them
all manually.

List of multiple classes can be now provided to --external option.
The Error class is now automatically included to externals list.

Stuff like: "Some string\
continues here".

It's rarely used, but I encountered it in some Jasmine tests.

Class tree bugfix

The number of static tabs now depends on if --welcome, --guides,
--videos and/or --examples options were specified.  Only the classes
tab is always on.

Also remove the <tpl> tag... leftover from JS version.

comment-to-markdown formatting has to be done after writing source files,
because doing the formatting in parallel breaks links between doc-objects
and source files.

Again makes things quite a bit faster as we don't write as big files.

Created ClassFormatter for doing this.

This speeds things up about 2x.

Remove code for using phantomjs entirely.

Previously refreshing the page while example tab open, would close all other tabs.
Now first loading all the tabs and only after that performing history navigation.

Clearing the page first and then loading the example.

Created separate examples.Container class.

Regression caused by switching to deferred rendering of all tabs.
