In its current implementation ( introduced in  4787eadd ), `variation_category` parameter of Inventory API require movements to be in the `predicate_category` table. The approach is to do a first query to get uids of all movements members of the variation and pass their `uid` to catalog. My guess is that this does not scale well. It also uses deprecated `where_expression` and generates invalid SQL when no movements match.

As far as I know, it is only used in [testInventory](https://lab.nexedi.com/nexedi/erp5/blob/ba541ad46e5c593f94fe1ebe79e99d67aafdecb1/product/ERP5/tests/testInventory.py#L1024). We could also consider dropping it, but keeping compatibility is easy.

This implementation just use `variation_text`.

[Test results](https://nexedi.erp5.net/test_result_module/20170502-1FDBAB66) are OK; there is one functional test failure but it really looks unrelated.

@yusei @vpelletier  @seb @romain do you see problems with this ?

Reuse code of delivery to ensure we can customize which item should be
in item table

This reverts commit 2ef67082

This allow customization, original init script is called by new script.

Performance is still not optimal, but should be better than before. At
least it does not assume that movements will be in predicate table.

Disable matplotlib interactive mode to avoid "ValueError: ordinal must be >= 1" error that sometimes happens when plotting datetime index.

Do not put links when no valid link exists. This makes copying values much
easier.
Do provide links to activity context and method.
Also, do not use TALES when it is not needed.
