Add support for membership criterion, to be able to define advanced trade model
paths with predicates.

This code was iterating in a dict and removing keys at the same time.

The second block was the same logic as the first, but using another variable
all along, except for the part where None keys are removed from dict. Change
this part to use the other variable used everywhere else in the second block.

Using an em html tag is enough to have to display the explanation
message differently, not need to wrap it in paranthesis, which does not
look so good in some languages.

formulator passes arguments, no need to look in request by hand. Also
this makes scripts easier to test if passed arguments are used.

This is required to be able to use solve divergence action

for now used in solver configuration only

This can help debugging test failures on test nodes

ERP5: Remove Capacity/GLPK: never used and broken since glpk Python module is not in ERP5 Software Release neither.

* Properly override WebSite Document in erp5_web_shadir by creating a new
  version_priority.
* Keep Web{Section,Site}TraversalHook in Product/ERP5/Document as these are
  not ERP5 objects. Also, add `kept_for_backward_compatibility_only` to
  importLocalDocument() to handle pattern where the Document class has been
  migrated but some code remains.
* Move WebSection_get*PrecacheManifestList Python Script from bt5 not depending
  on erp5_web to erp5_web_renderjs as this is required by CodingStyleTest
  (WebSection being now in erp5_web).

When a first migration was reverted for any reason (e.g. ConflictError),
the assertion failed because __setstate__ was not called yet to fix the
class back to the old one.

Fixes Active Process' "hasActivity" method when that document's uid is >2**32.

erp5_officejs_support_request_ui: Add begin date to the query when user click on "Last Month Activity"

The filter when the user click on the "Last Month Activity" chart filter Support Request only by status (Submitted / Open / Suspended / Closed). So on the table "Recent updates", all the support request with the chosen status appear. There is no filter by "Begin Date" for the last 30 days, which is no coherent with the "Last Month Activity". => It should appear only the support request with the chosen status with a begin date < D - 30 days

Base_viewDict does not produce valid html, showing the dict using showDict is enough

- use html5 doctype
- don't use i18n: tags where they are not processed
- use class instead of id for elements that are repeated
- remove Content-*-Type meta that are reported as invalid by nvu

this class does nothing and does not seem used
