Useful for showing some about-information for the docs.

Added code to Rakefile to display the current JSDuck revision there.

Added extra div surrounding each subsection.
Subsections now also get correctly shown/hidden.

Only static members marked with @inheritable will be inherited.

More granularity plus tests for mixins.

All static members are now exported in separate "statics" section,
alongside "members" section.

Rendering static members in separate section in class overview
page, and added "static" label to distinguish static members in menus.

Handle the renaming in UI.  This way we can more easily check for
which method is the constructor as we can just check if name equals
"constructor".

This also fixes the bug of inherited constructors not having "new"
in front of them.

This time it's much better, nowhere near the big hack it was before.

With current ExtJS 4.0.2 branch the old code fails.  Replaced one
hack with another.

Always show only the first sentence, no matter how short it is.

Now the index page component is separate from components dealing with
rendering parts of docs for particular class.

No more passing the docClass config option to TabPanel and Overview -
it's not used anyway.

So we can call it similarly to cls.Overview.

Also no more pass initial class config to the header component.

A verb is not really a good name for class.

More descriptive.

Instead of putting them directly to class hash, we create a sub-hash
for members.  This way we don't have to list all the member types
in every place where we want to loop over all the types - we just
loop over the :members hash.

Additionally it will make easier in the future to add a separate
group of static members.

This was too confusing.  We still have @member in doc-comments,
but it's translated to owner internally.

Currently not used, so throwing out for now.

Currently I implemented it with opacity, but I'm sure a designer
could do a better job.
