I really don't like to pollute every single file of JsDuck with
GPL license header as the GNU guys suggest.  So I just include it
into the main jsduck.rb file.  No harm done, I hope.

The index.html file already defines ext namespace.

Plus some documentation for the point of Merger class.

Package nodes aren't created for packages beginning with Uppercase,
except when they are at root level.

But it was fun, nonetheless.

Replacing with simpler (although a bit repeated) code.

Plus tests to catch this bug.

This prevents ugly empty lines at the beginning of almost all
code examples in ExtJS documentation.

Plus some re-arrangements in README.

Markdown-stuff no more wrapped inside <div class="markdown">.

Unified the formatting of parameter lists and normal lists, so
that creating list with markdown results in something similar
created with built-in parameters list.

Paragraphs now always have margins and aren't crushed together
in method comments.

<strong> is no more has display:block - that was just insane.

Finally added DOCTYPE for touch of sanity.

Removed needless cruft from class properties list:

- Package name can be seen from class name.
- Class name can be clearly seen from heading.
- Defined in is currently not implemented.

* Fixed indetation and spacing.
* Removed unused rules.
* Combined duplicated rules.
* Prefixed most stuff with .body-wrap class.
* Ordered things using some logic.

The source comes from official ExtJS documentation (included in
ExtJS release package).  This includes the minified version of
ExtJS 3.3.1 with gray style.

The original ext-3.3.1/docs/resouces contained a lot of unused
CSS and image files - these were all excluded as unnecessary crap.

JsDuck now includes --template command-line-option to specify
alternate template to use.  By default the template/ dir included
with jsduck will be used.

Added TreeIcons class that extracts icons from tree.

RDiscount is way faster and it doesn't throw errors for malformed
HTML like Maruku - so we can treat all the comments as Markdown,
plus we can mix HTML and Markdown.

Actually RDiscount doesn't throw any errors at all, whatever we
feed it.  If it doesn't recognize text as correct Markdown, it
doesn't complain - it just leaves it as is, which is perfect for
us.

There are some minor issues still with it:

- <pre><code>-s getting nested when parsing Ext source.
- Even one-liners are wrapped inside <p>...</p>.

But these are pretty easily solvable.

This way we can later style the markdown-HTML differently.

It does now more than just links replacement.

Expanded DocLinks to also perform Markdown formatting - but only
when doc-comment doesn't already contain HTML.  Event then we
might get error when parsing it as Markdown - in that case we
silence down the error and continue without rendering it as
Markdown.

Plus some ExtJS strangenesses in use of @member.

Reverse-engineered the behaviour of ext-doc when merging multiple
doc-blocks for the same class.  Not 100% the same, but mostly.

Now finally we have support for most of the stuff that ext-doc does
on parsing-side.  The output-side needs quite a bit more effort,
but parsing and analyzing of input seems almost complete now.

This siplifies tests that only need to include the class
they want to test and not worry about including all the
dependencies too, as these will be automatically included
by the class itself.

Additionally the header of each file gives a nice overview
of the direct dependencies each class has.

I copied the previous lump-all-together-into-main-file-design
from some ruby project in github, thinking there is some value
in doing so.  Well there wasn't...
