In 1.9 the Hash#select method returns a Hash, but in 1.8 it returns an
array which can be converted to a hash using Hash[] (when passed a hash
it will just pass through) - so now the code will produce a hash in both
1.8 and 1.9.

Created a #saveNew method directly on model, which ensures that
when we add the comment, we automatically mark it as read for
moderators.

Mongoose documentation doesn't list such parameter, and in comments app
code it's nowhere used.

This way it's also similar to ExtJS docs where there is a extjs-build/
dir.

Expanding when more lines added.

Additionally remove enterMode config, which is no more supported,
but the existance of which doesn't seem to make a difference.

- When comment edited.
- When deleted comment restored.
- When additional comments appended to comments index page.

Eliminate separate :tests task.

Move --stats option below it (keep it still experimental).

Adjusted styles to allow for text labels - I currently don't have
suitable icons at hand.

Extract BatchRunner component, responsible for actually running the
tests.

The Index view then simply commands the BatchRunner and listens events
from it.

All this resulting in much simpler and actually even shorter code.

So we now have a --tests option and all related modules are named
tests, not doctests.

Also some refactoring of the DocTests view.

Add :type field to tell them apart.

Created Stdout class that merges arrays from multiple sources together
and then finally writes all to STDOUT.

Guides HTML is now placed inside guide hashes and can be easily accessed
from there when looping over with guides.each_item.  But when calling
the #to_array method, :html keys are filtered out, so it behaves like
before and can be placed inside Docs.data.guides.

I picked a font in Google Web Fonts that looks most like the klavika-web
from Typekit.  Only a designer will note the difference.

The whole Typekit experience kind of sucked:

- The site was down from time-to-time.
- The font was only available for sencha.com, so anybody generating
  their own docs with JSDuck would not get the nice fonts.  Also the
  docs withing ExtJS download didn't have the nice font.  etc.
- Recently the font also stopped working from localhost.
- The JavaScript for adding this *one* font was needlessly big, with
  Google Web Fonts it's just one <link> element.

Keeps the iframe code much simpler as it now only needs to call
the passed in callback method with true or false.  Previously it
needed to call a static method directly on InlinePreview class,
which was quite ugly.

Touch examples with "raw" option now work as intended.

- Use double-click for running single example (add help text for it).
- Change title.
- Simplify status text updating code.
- Other smaller tweaks to layout.

Created InlineExamples class that extracts examples from already
formatted code and writes them to inline-examples.js file.

The front-end now only needs to load this one file with all examples in
it.
