…di#550

* runScheduler was never being called

* Convert Themes library to use requirements
* Convert register_themes.php to use requirements
* Convert plugin helper to use requirements
* Move theme js to use Requirements library
* Stop passing script tag in api_url config settings.
  Set url in settings and handle the actual tag through Requirements
* Fix path for file to stop it suffix'ing remote urls
* Render Requirements through Themes library for frontend ushahidi#338
  This makes it easier to update old themes as they can still use header_block()
* Make admin/members layout call Requirement::render() since they
  don't have header_block()

* Only include jqplot js+css if needed
* Remove inline css and use class instead
* Remove graph div when disabled

* Rename style.css in other themes to avoid overriding default style.css ushahidi#301
* Move the Requirements calls from register_themes.php into Themes library

* Split style.css into base.css and style.css
* Tweak alerts radius map not to use .map class
  Use map-wrapper class instead as this avoids conflicts
  with div.map on main page. This Simplifies base.css so
  it doesn't need to style the map-wrapper too
* Move accordion styling to its own file
* Add basic style for reports submit and get alerts in base.css
* Remove some old unused CSS too

…shahidi#550

* Allow themes to specify addition css/js files to include in readme.txt

* Update existing themes to specify JS files

… css ushahidi#301

* Can now override openlayers.css and jquery-ui-themeroller.css

  then media/css

* Pass api_url_all as an array of urls, for easier use with Requirements
* Make Requirements handle arrays of css or js files
* Move some admin js to media/js/admin.js instead of inline

…hahidi#338

* Start calling requirements from pre-render event for main controller too
* Backend and frontend requirements are enabled through a variable on
  Themes.
* Slider, timeline and hovertip are now enabled like other js libraries
  rather than always included or include based on $main_page
* Removes unused flot js and excanvas js
* Openlayers and jquery-ui-themeroller are no longer themedcss but included
  early so can be overridden via theme css files anyway.
* Move admin header/footer block render to pre render event

* Replace jquery.ui.min.js with version including accordion
  Previously only included features used in the admin.
* No longer using the google CDN for this as per ushahidi#365
* Previously the admin used its own jquery UI, now both admin
  and frontend use the same version

Conflicts:

	application/views/admin/layout.php

* Pass themes object to themes_add_requirements action
* Add event for adding requirements before admin/frontend stuff

* Give all CSS/JS uniquenessIDs, based on filename if not supplied
* Require uniquenessID on custom CSS/JS/HeadTag
* Handle handle write_js_to_body option in Themes library not
  Requirements
* Give themedCSS a better uniqueid
* Split out Render by type instead of location
* Remove combined files code - rewrite later
* Remove auto js/css extension adding magic
* Add notice for missing JS/CSS files

* Add option to requirements to support combining files
* Add groups for base and admin combined files
* Move admin/all.css to admin.css so url() links work when combined
* Add CDN support for combined files
  * Auto upload combined files to the CDN
  * Fix minor issues in Cloudfiles classes -
    probably related to PHP 5.4
  * Make cdn helper handle files not located in media/uploads
    or already with full path.

* RTL languages are detected based on special core.text_direction
  i18n string
* If language is RTL we check for CSS files with the same name but a
  -rtl suffix
* Support -rtl versions of combined files too.

* Auto combine CSS files for themes
* Including the Minify_CSS_UriRewriter to fix url() links in theme css
* Include CSSMin to minify CSS files
* Add extra static call CSSMin::go()

Now using . as separator instead of -
As per feedback from @ekala this is a better match for the existing
naming convention.

* fix block() to handle IDs and full filenames
* fix path_for_file() to handle query strings w/o mtime
* fix delete_combined_files()
