Clean up HTML files, Gruntfile and remove index-phantomjs-tmp hack

Consistently:
* Use <!DOCTYPE html>.
* Use lowercase element tags.
* Indent <head> from <html>.
* Use <meta charset="utf-8">.
* Indent <script> and <style> content from open/close tag.
* Put <link> before <script> when in <head> (in ve/test).
* Use .html instead of .php for indexes where PHP is no
  longer used.
* Use the same license header as we use elsewhere (/*! instead
  of /** and no @file)

Gruntfile:
* Include the new .js files in jshint (demos/**/*.js).
* Order buildloader keys in the same order as the directories
  they go to (alphabetically).
* Add missing jshint patterns:
  - .docs/**/*.js
  - build/**/*.js
  - modules/ve-wmf/**/*.js
* Add missing qunit test:
  - qunit.unicodejs
* Add missing watch patterns:
  - .jscs.json
  - qunit.unicodejs

Also:
* Moved relatively large pieces of script into separate files
  so that they are less repeated (though .template) and also
  able to be linted properly.
* Fixed jshint warnings in newly-created trigger.js and demo.js.
* Moved <script> elements already in <body> to bottom of <body>
  (in ve/test and eg-iframe).
* Moved <script> in eg-iframe from <head> to <body>.
* Fixed buildloader grunt task to use a non-\n whitespace match.
  for the start as well, the newline before the placeholder was
  being stripped.
* Removed the (now obsolete) index-phantomjs-tmp hack.
