Revision 747d4e6db7cbf09454ef36ce896f466022657f9b

Doc:

- param_view_siteaccess_compare_overview.en.md has seen a small correction and some minor improvements in visual presentation

CSS:

- bundle.css: removed some (now) obsolete css

- parameter_display.css: Added an animation for visual loading feedback

JS:

- SearchBarUtility.js:

1. Added that the search is repeated, when changing the search mode, so that the behaviour of the search is more inline with the expectations of a potential user

2. Persisted the search state in the url, this allows sharing a link with a search already running when opened, this provides more control and more feedback for the user, when using the site

- SiteAccessDifferencesHighlighter.js: Persisted the highlighting state in the url too and allowed users to share that particular state of the site, making it more responsive and added visual feedback when the highlighting takes place

- SynchronousScrollerUtility.js: Persisted the synchronous scroll state in the url so that the user has more control and options regarding the view and added visual feedback which indicates when the function is being loaded

- Utility.js: Improved the url state functions a bit and added urlencoding to all of them, fixed a bug, where the states wouldn't be removed correctly and added a method to retrieve the value associated with a state in the url

Views:

- Changed the help teaser to now appear directly under the main headline of the header, so that its design fits better with the overall look and feel of the backoffice

Composer:

- composer.json: Added a few details to the description and the tags
