Breaking word everywhere leads to a really ugly rendering

[json_style] Support manual pagination in ListBoxes when the underlaying script does not support limits

green for success and orange for fail

erp5_hal_json_style: relationfield is rendered as no editable with empty value when user can't access related document

cause ooffice_text was launched

Fixing testCloneObject unit test
The problem was that upon installation the generic list view became the default view of Foo Line thus was missing actions like Clone. This one is particularly hard to find because diff does not show this problem and moreover newly created action on a Portal Type is placed last by default. Thus this is a random error.

erp5_officejs_support_request_ui: Use shorter bar title which can make the title more visible on the small screen.

When a user clicked an item on a chart. The listbox in below only show the items which related to that item. This is done by generating a search criterion according to that chart item. Then provide this criterion as "extended_search" to update the lisbox.

Restricted: Allow datetime module class attributes.
    
To allow the class attributes, we add a helper method ``allow_class_attribute''.
 Why addng this is because allow_module can allow instance methods but not class
 attributes.
 For example, datetime.datetime.now(), datetime.datetime.max, dict.fromkeys(),
 Decimal.from_float(), epoll.fromfd(), itertools.chain.from_iterable() are class
 attributes in Python 2.7.
    
 Also, add a special in-advance-import for datetime.datetime.strptime().
 It is because datetime.datetime.strptime() imports _strptime by C function
 PyImport_Import which calls
 __import__(name, globals, locals, fromlist=['__doc__'], level=0).
 The "level=0" is not supported by AccessControl in Zope2. At the same time,
 the dummy from '__doc__'  is neither allowed in it by default.
 Therefore we import _strptime in advance in this monkey patch file.
 This prevents both importing _strptime with level=0, and accessing __doc__,
 when calling datetime.datetime.strptime() in Restricted environment.

erp5_officejs_support_request_ui: Check the "Empty Criterion is Valid" checkbox in "Unsafe" web section.

Without check the "Empty Criterion is Valid", the web section will return nothing. But due to a bug, the web section will return all documents anyway. This should be checked.

Rename `rjs_gadget_erp5_pt_listpage*` to `gadget_supportrequest_pt_listpage*`.
Rename `rjs_gadget_erp5_pt_form_view_discussable*` to `gadget_supportrequest_pt_form_view_discussable*`.

Web pages which ID starts by `rjs_gaget_erp5` will be include in `erp5_web_renderjs_ui` bt5. We want the custom page template only be included in the `erp5_officejs_support_request_ui`.

Rename the title of left chart to "Support Requests Pipe", right chart to "Last Month Activity"
