To Compare a "screenshot" of a DOM element with a reference snapshot.

This check supports the following parameters:
 *   locator - an element locator
 *   misMatchTolerance - the percentage of mismatch allowed. If this is 0, the
      images must be exactly same. If more than 0, image will also be resized.

to get stable sort and prevent "random" test failures.

"Restore" sounds a bit strange to me in this context.

So that we can wait for this in the tests

This is incubator-echarts-4.1.0-release/dist/echarts.min.js from
https://github.com/apache/incubator-echarts/releases/tag/4.1.0-release

This reapplies parts of 9a84ef83 , but a
different server side approach:
 * use portal_workflow API to count worklists
 * introspect workflow to build queries
 * use translated state in the query, trying to be a bit more user
   friendly. We could do for portal_type as well.

This workarounds #20180907-24A654C a problem with queries generated by
gadget worklist does not seem to support complex queries with multiple
values ( local_roles: ['Assignor', 'Assignee'] ). This code generates
queries:

```
( ( local_roles:  "Assignee" OR local_roles:  "Assignor" ) AND portal_type:  "Support Request" AND translated_simulation_state_title:  "Opened" )
```

where the previous version generated queries like:

```
( portal_type:  "Support Request" AND simulation_state:  "validated" AND local_roles: (  "Assignee" OR  "Assignor" ) )
```

which did not match anything. Maybe because local_roles is handled
differently in catalog

This reverts commit 9a84ef83.

Eventhough there's a delay due to cache, the default worklist
implementation is efficient and worklist is translated.

Also:
 * don't immediate reindex, this is a coding crime
 * don't search catalog by ID, use direct module access

To make it easier to test worklists and dashboard.

SR-15 Crashed! is Opened
SR-16 Boom!  is Suspended
SR-17 Done is Closed

Because worklists tests expect to run with ERP5TypeTestCase user, and this test uses another user.

The timeout of 10 seconds was too short for some machines

Drop failed activities instead of retrying execution and expecting it to
both fail and do something (execute alarm, then index result).

This also reverts commit f3519857.

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.

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
