From reimporting spreadsheet manually extracted from "Autorité des normes comptables" website
http://www.anc.gouv.fr/files/live/sites/anc/files/contributed/ANC/1.%20Normes%20fran%C3%A7aises/Recueils/PCG_Janvier2017/pcg_janvier%202017.pdf

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`.
