Optimize sorting of list of test suite to be executed by test nodes.
We give priority to test suite with older test results. This allows
to have test node resources in a more fair way.

The activeSense method is doing more than calling the alarm script, it also change
the user. Without using activeSense, the alarm script will be called under the user
doing something on test node/ test suite, and this could conduct to different results
than if it is run with the nobody user.

with this, we can reuse the test and add more files that should be
ignored.

In some cases 'total_size' was duplicated in selection and request causing listbox rendering to fail.

__ac_persistent set to 0

<input login `request.get("__ac")` > removed

When the login form is rendered, the login field is not already filled.
We assume that the "__ac" cookie is deleted, so no need to generate the
login name server side. It also avoids to use old "__ac" cookies.
Browsers are already able to autocomplete them just by clicking on the field.

This alarm will check if a cache is assigned to some files in portal_skins.
If a file has no cache manager, it triggers a Problem.
When solving the alarm, `http_cache` will be assigned to uncached files.

In Base._getAcquiredCategoryMembershipItemList, replace broken code by an exception.

Step to reproduce:
- change preferences once
- go back to previous page with browser button
- submit again
- exception in KnowledgeBox_baseEdit because 'form_id' is sent twice
  and is transformed by Zope into a list
