Best to `rm -rf node_modules`, then re-run `npm install`.

Instead of EXT_DIR --> EXT_BUILD.
Additionally added TOUCH_BUILD.

Also now using the constants themselves all over the code, not mapping
them into class variables.  This means the build will only fail if a
particular variable is needed.  So you don't need to define ANIMATOR_DIR
if you're not planning to build animator docs.

I'm not adding a new warning type to allow turning this off.
Instead everybody should just upgrade. No exceptions.

In 4.1 the View class also handles data attribute and things
will crash if we have our own special-purpose data in there.

At creation of Tabs component the overflow button creation was
triggered twice - first by afterrender, then by resize.  Removed
the first as having it twice caused a crash in Ext JS 4.1.

Previously it happened to be required by search controller.
But one shouldn't rely on such a coincidence - each view should
declare all the classes it depends on.

The Settings store happened to be instantiated by Classes controller.
This was just a coincidence that Docs.Settings class relied upon.
Now the store is created inside the Settings class itself when it's
initialized.

Removing the "#" from the beginning of history tokens was a mistake.
Also the case of no previous history token was unhandled.

Now comments can be marked as read from normal comments list of a
class/member.

The "read" status of comments is shown in all comment lists when
user is moderator.

Changed the styling of "read" badge into more prominent.

The code relied on the order of events being fired.  It expected that
when clicking tab close button the "click" handler for close button
will be invoked before the "click" handler for the whole tab.  This
worked in the majority of browsers but not in IE8 where the events
fire in the opposite order.

Now checking the event target inside tab click handler to see if
close button was clicked instead of relying on the close button handler
to set a flag.

This also fixes the issue of tabs sometimes not activating when clicked
in IE8.  Was caused by justClosed flag being set but not unset.

The return value of Array.indexOf was bogusly compared to false,
but #indexOf returns -1 not false on failure.

The official extjs-4.0.7 release has a bug in cors support where
it mistakenly checks for Ext.isIe instead of Ext.isIE.

Because the font-set is only registered for sencha.com and localhost,
running the docs app at any ther domain will get 403 error when
attempting to load fonts from typekit.com.

We should probably completely move this code to sencha-specific config
files.

Those files haven't existed for ages.

Forgot to update version number printed by --version.

Because {Type=} defined an optional item, it was taken granted that
just {Type} would define a required item.  Not so fast - while
params default to being required, configs default to being optional.

Makes it easier to find the close-all-tabs feature.
