PURPOSE Reorganize addon according to guidelines, helping finding and updating code. SPECIFICATIONS Correctly split data into separate files. A lot of content was put a bit randomly in data files, leading to a hard discovery of code and features. We also fix duplicated attachments definition, both in mass_mailing_data and ir_attachment files. It has been merged into the attachment data file.
