for editable id fields

This field is required, because ID are really required in Zope so we have to make an exception to prevent a Site Error message and has an external validator checking that the document has no pending activities.

getObject is not public API. Bonus is we can do one query for all uids

Since it's allowed for multiple sections from same group to post
transactions on the bank account from the parent sections, the bank
reconciliation should use the same logic to be able to reconcile
transactions from any section.

This was not following the signature of the real method

If we leave sort_column empty, catalog/listbox will incorrectly guess
the sortable columns.

There is a related key for source_title that does not work here (because
this method selects movements, and movements categories are not indexed,
so lines which acquire source from their parent are filtered out)

Conflicts:

Some listboxs using it were using default_sort to inject this
automatically, but it's better to do this directly in the script, this
way the script can be reused.

I'm not really convinced the script should honor sort_on parameter
received in kw, because misconfigured listbox can inject some parameters
that would cause more table to be joined.

this is still unfinished work

no need to do catalog here

this way callers does not have to lookup explanation by catalog themselves

This uses caching (which will probably never be hit here), prevent
problems if delivery_uid is null (which should not happen) but it's
consistent with other brain methods.

* explain how to use
* remove useless getTitle method
* fix indentation

merge rebased commits of nexedi/erp5/merge_requests/321

with:

`git cherry-pick nexedi/mr/321...47eba793~1`

Changes:
 * indentation and whitespaces between function and (. ( tips: use ignore whitespace for review)
 * usage of `new`. Some RSVP.Promise where not using `new`, some RSVP.all had an extra `new`
 * fix a "weird condition", javascript does not evaluate (a <= b <= c) same as python
 * change `var` declarations one per line, to be compatible with
   upcoming jslint version. Use a vars: true  directive so that jslint 2014-04-21 is also happy  (
   see https://stackoverflow.com/questions/34862541/expected-and-instead-saw-jslint-multivar-setting )
 * in function definitions: rename unused arguments as `ignore` or remove them when possible ( when they were last )
 * use named functions ( for exemple fillDialog ), otherwise jslint complain they are not in scope.

Otherwise, the event handler is set multiple times on the same #qunit-fixture element

It causes {msg: "jsPlumb: unknown connector type 'StateMachine'"} problem when jquery was already loaded

because it adds an action to edit business processes

This is to comply with
