Copy-paste data fixes

* Assign cut/copy/paste events to the document so that
  they are triggered when the CE doesn't have real focus
  e.g. only a FocusableNode is selected
* Use clipboardData.setData when available. The key can
  be stored and retrieved perfectly in text/xcustom but
  this technique doesn't work in FF or IE
* Just use text content for key as this is what is written
  to the clipboard, so this can be used directly without
  having to get the content from the pasteTarget.

Give document real focus after cut

If only a FocusableNode is selected the document doesn't have
real focus, so we must do it manually.

Kill domAttributeWhitelist in favor or renderHtmlAttributes

domAttributeWhitelist wasn't actually being observed. Instead, we
already had the code in place to treat renderHtmlAttributes as a
boolean/whitelist/blacklist hybrid, it just wasn't used that way
yet.

This makes the interface nicer and fixes the bug where all attributes
(including data-parsoid and even things like onmouseover) were
rendered by CE.

Avoid crash after ve.dm.Surface.purgeHistory().

The selection property is never null; it is initialized to Range(0,0).
If it is set to null in purgeHistory(), the next call to
ve.dm.Surface.change() will crash.

Make ve.dm.Surface.{start,stop}HistoryTracking idempotent.

Add a little robustness, guaranteeing that we don't end up with multiple
history tracking tasks running, leaking one, or try to clear a non-running
interval.

Don't render <meta>/<link>/<style> tags in GeneratedContentNode

There is no good reason why we'd render these tags, and their presence
causes Chrome to crash while cutting across them.

Actually use GeneratedContentNode in AlienNode

ce.AlienNode was mixing in GeneratedContentNode, but wasn't actually using
it properly. This commit fixes this so that AlienNode can benefit from
the <meta>/<link>/<style> stripping code in GeneratedContentNode.

Also added a getHashObject() function to dm.AlienNode to summarize the
domElements attribute because ve.getHash() chokes on it otherwise.

Followup 41a4b3fb: use .not()

I claimed that it didn't preserve text nodes, but it does. It's just
that there's a bug where it doesn't preserve text nodes if the selector
passed to it is too simple, but 'link, meta, style' is complex enough
to avoid triggering this bug.

Detect outdated pending post KeyPress handler

modules/ve/ce/ve.ce.Surface.js
* Schedule the post-keypress async handler in a way that can be cancelled.
* Cancel it and run the handler immediately if another key event happens.

When pasting, try to use original range

This functionality was (accidentally?) removed by I8f8a240a. It
stops us from over-zealously balancing data when we can get away
with just pasting the original selected range (e.g. it always wraps
collections of text and content nodes in another paragraph).

Disable inserting/changing references when surface widget is empty

This listens to change events on the surface and checks to see if
there is more than just an empty paragraph node.

AnnotationInspector insertion over blank selection

This commit fixes two issues with insertion of annotations in blank space:
* LanguageInspector issue with inserting an language annotation inside any
  whitespace (selection of space between words or collapsed selection in
  blank line)
* AnnotationInspector issue with collapsed selection inside slugs. If
  the marker was in a slug collapsed selection, activating
  AnnotationInspector would expand the range to the closest word (on the
  next paragraph). This commit makes sure the expansion for the next word
  only happens if the selection is outside a slug.

Add support for single scripts, styles and debugScripts

Objective:

* Make makeStaticLoader.php compatible with ResourceLoader module
  definitions that use a string instead of an array with a single element
  when describing a single file

Changes:

maintenance/makeStaticLoader.php
* Cast styles, scripts and debugScripts to array when iterating over them
