As for xhtml_style, always use Base_viewRelatedObjectList by correctly filling the REQUEST, and let it render as any other form.

From reimporting spreadsheet manually extracted from "Autorité des normes comptables" website

and imported using Base_importGapFileForm

There are lots of changes, some are just spelling a few accounts have
been removed, for example based on this legislation change (
http://www.anc.gouv.fr/files/live/sites/anc/files/contributed/ANC/1.%20Normes%20fran%C3%A7aises/Reglements/2015/Reglt2015-05/Reglt%202015_05%20_%20instruments%20financiers%20%26%20operat-de%20couverture.pdf
) and maybe others.

The script from Base_importGapFileForm is old and buggy ( the
hand-written csv parser strips comma ). Also I did not change the
descriptions and just kept them when adding the changes one by one with
`git add -p`.

erp5_accounting_l10_fr: FEC: Allow to specify from_date instead of using the last Accounting Period.

For instance to build FEC reports on a daily basis.

erp5_accounting_l10n_fr: 'at_date' in FEC Dialog requires month/day so these should be in the generated filename too.

erp5_accounting_l10n_fr: FEC Report: Allow to group by ledger or ledger+portal_type in addition as per portal_type (the default).

This required refactoring the source files as the implementation was
portal_type-centric. This adds a dedicated Python Script with ProxyRole=Manager
to create Active Processes and thus avoid executing code as Manager as much as
possible.

erp5_accounting_l10n_fr: Depend on erp5_deferred_style (FEC Report calls ERP5Site_notifyReportComplete).

officejs/gantt: display manufacturing orders on gantt of production and make dhtmlx gantt supporting colors
