This reverts commit 35b2c024.

Allow edition in the new UI

This make everything slow as hell and prevent to quickly save.

This MR continues !1074  (Ivan's mistake)

See merge request !1077

Add a business template that can configure a default ERP5's installation. This bt5 is to be used in Scalability and Deployment tests ONLY.

Fix script name

Reduce the time required for a user to scan a multiple pages PDF.

It has been fond that the slowest part of the scanner dialog was to wait for an image to be uploaded before being able to scan another image.
In order to improve this, it has been decided to allow user scanning a document even if the previous image is not yet uploaded.

See merge request !1034

Having WebPage_viewAsWeb in default skin selection break other sites
relying on default behavior of erp5_web.

See merge request !1071

erp5_document_scanner: Rename web_page_module content IDs to not conflict with erp5_web_renderjs_ui path pattern.

- Stop relying of CSS hide/show attributes. Instead, only put needed elements in the DOM.

- Upload images asynchronously to improve the usability

Add a tales expression as default field value. The default value is a JSON containing 2 keys:
* the relative_url of an active process
* the list of active process image content to aggregate
By default, when the field is rendered for the first time, this tales expression is evaluated and a new active process is created at that point.
So, default json is like: {active_process: 'portal_activities/1234', image_list: []}
* store the active_process relative_url in the gadget state in the render method
* store the image_list in the gadget state in the render_method
* change getContent method to send a json build from the active_process and image_list state

- Change the gadget checkValidity method to return false when:
  * no thumbnail has been generated
  * a thumbnail upload is in failed state

- POST image cropped to backend
  * change the `extra renderjs` parameters list to pass a Python script to call when a new image is cropped.
  * change the gadget to use jio.util.ajax with the script full url (provided by the server)

- Translate and Update i18n info
- Ajax must return a active process image content UUID
- Add spinner in button to show that we are saving it in background
- Add reference to Active Process. With this, we can search easily active processes used by document scanner and remove them
- Add an alarm which will delete outdated (>5 days old) active_process created by the dialog.
- Improve code to switch cameras in mobiles with more than 2 cameras
- Display intermediate image after get orientation and instantiate Cropper

This script can be used for deployment tests which do not require these changes thus make it configurable but still keeping the default behaviour as it was.
