After clicking on "Documents", we need to wait for the listbox to be loaded before doing anything else. In particular, if we do a search after clicking on "Documents" the listbox is loaded twice (once after clicking on Documents and once after clicking on search). If we don't wait for the listbox to be loaded before doing the search, the search macro might end too early.

Add manifests to make the app a progressive webapp. There are 2 manifests : one
during the installation process (while the app is loading) and one for the app
itself.  Note that the "start_url" parameter is made for the officejs app URL
([your_app].app.officejs.com/[release_number]). It doesn't work on an ERP5
instance ([instance_url]/erp5/web_site_module/[your_app]). If you want to make
it work on the ERP5 instance for testing purposes, remove one "../".

Update the Javascript Editor logo according to Vincent's wishes.

The app will be labelled "Javascript Editor" for now but the domain name will be codemirror.app.officejs.com.
Update dropbox_app_key (generated by Vincent).
Reorder totally the apps on officejs appstore (as suggested by Vincent).

Don't change anything, just make it pass the linter.

In web_site_module/predecessor_test_web_site/section_with_content_page.

This publication_section was already sel on the web section (but seemed not active ??), but not on the web page. Then this commit just adds the missing category and update the web page

Those classes were used by JQuery Mobile.

The tests are exactly the same as for text editor (except there is no
"migration test" which was not really to test TextEditor)

Codemirror app is now using the same mechanism as text_editor. For now, it has
exactly the same features as text editor but it will create "Web Script"
instead of "Web Page" documents. The codemirror mode is forced to "javascript"
and the content type of the document if forced to "application/javascript".

DiffTool: removePropertyList function should be working same for both ERP5 object and dictionaries of ERP5 object properties

Before we use to neglect removing some properties from ERP5 object properties' dict, which led to error in case of use
of DiffTool for Historical Revisions dict. Thus, its important for removeProperties function to act similar in both
cases.

Also, add `base_data` in attribute_set to be removed because `data`, `base_data` and `text_content` are same

This is essential to have better aesthetic of Deepdiff diff for tuples.
In general, we treat iterables as long string so as to bypass the complicated
diff for iterables provided by DeepDiff, but for tuples this was creating a
problem as it was not possible to understand the diff properly.

Hence, by soting them, we get more understandable diff for tuples.

Also, there is no need to override `__diff_tuple` function as it is itself
dependent on `__diff_iterable` which we already override.

Following convention, it makes more sense to use view mode for DiffTool view.
Also, we don't need selection as of now.

Also, update the tests

View wise, the date and path for new version/obvject should be on right side which
in our case is `your_second_date`. Thus, the case where we run diff action on single
object, the right side should show the current version and the left side shoule show
the last version.

zope.conf default encoding is also used for responses and converters, so
for consistency we should also force default encoding there.
This is especially useful when running tests, because zope.conf is not
used and default values are used.

https://tools.ietf.org/html/rfc4329#section-7 states that text/javascript is obsolete.

Doesn't really matter in the end because WebPage_viewAsWeb forces the content type.

In HTTP/1.1 , when not specified , charset detault to ISO-8859-1

https://tools.ietf.org/html/rfc2616#section-3.7.1

> media subtypes of the "text"  type are defined to have a default charset value of "ISO-8859-1" when   received via HTTP

Zope adds a charset with default encoding (
https://github.com/zopefoundation/Zope/blob/2.13/src/ZPublisher/HTTPResponse.py#L512-L515 ) but does this only for text/ type, but we serve our javascript as application/javascript
