Also move History.js too inside app/ directory.

Merge in updated mvc with history support and other fixes.

Turns off warnings, of which there are currenly a lot.

Created Logger class for managing the warnings centrally.

Instead of the whole original {@link ...}

Running JsDuck on ExtJS SDK will generate a whole slew of warnings.

The previously hardcoded values are now in sdk-vars.rb, which is
ignored by git.

This is a real quick-and-dirty solution, but works :)

Resizing the browser window wasn't working due to a scope error on the
resize timeout.  Using Ext.Function.defer to be able to easily bind
scope to the deferred function.

Don't need this for now.

Simply ignoring this tag for now.

OverviewData is now in json file, which is parsed by JSDuck and
checked for missing classes.  After that it's written to
output/overviewData.js

The lot of changes in overviewData file are because the file wasn't
valid JSON - it used single-quotes and some items weren't quoted at all.

Ordered command line options alphabetically, adjusted line lengths,
and added blank line between each option.

Much clearer now.

Also renamed write_json to write_class (it now writes jsonp instead,
but writing class docs is it's primary purpose).

Parsing guides README.md files is now done inside JSDuck, and enabled
when --guides=/some/path option is passed in.  As an added bonus, the
{@link-s} inside guides now also work.

Like with class documentation, we create .js files for guides to
load them over JsonP.

Instead of pure JSON-export JSDuck now exports a .js file for each class
with the following syntax:

    Ext.data.JsonP.Ext_grid_Panel({...json-data-here...});

On JavaScript side we specify that the name of callback function should
be "Ext_grid_Panel" - this way we can use the JsonP deterministically,
knowing at JSDuck export time which names the callback functions will
have.

Note that we are passing callbackName option to Ext.data.JsonP.request,
which is not present in ExtJS-4.0.0 - I just added it to ExtJS SDK and
sent a pull request.

Docs.History now uses Ext.util.History instead of history.pushState.
