Modules should have the business_application base category set in order to classify them. Normally, the code helper set this category on module creation (https://lab.nexedi.com/nexedi/erp5/blob/master/product/ERP5/bootstrap/erp5_core/SkinTemplateItem/portal_skins/erp5_core/ERP5Site_createModule.py#L15), but it is often forgotten to commit it (as it should be defined explicitely in template_portal_type_base_category_list's bt5 property.

This commit tries to fix it globally in all bt5s, using a script : https://lab.nexedi.com/snippets/259. I have tried to respect file modes, file encoding, alphabetical ordering, and "\No newline at end of file" issue in order to not generate useless diffs when other people will commit on these files later.

@jerome , @vpelletier , @kazuhiko , @seb : could you have a check to the file formats to tell me if anything is wrong ?
