When starting the clickEverywhere test with enterprise modules
installed, it happens that Odoo web client is not yet fully loaded.
In this situation, the test does not find any app to test.
With this commit, an attribute is added to odoo to check if the web
client is fully loaded.
This commit adds a new js test in web that enters each app and click on
each view switcher, each menu and each search filter.
This test is tagged '-standard' and 'click_all' as it could last a long
time, that way it's not executed by default.
It could also be started from the browser console with
'clickEverywhere();'.
