This patch makes sure that there are minimal changes when loading and saving a file with change tracking. - the authors are assigned a buffer_id, such that when the file is saved, they get the same id, - the authorlist is sorted according to the buffer_id, - the buffer_id is written to the file in the author list (file format change) - the ids start with 1, because 0 is internally reserved for the current Author, - when writing the file, the current author is assigned an id if he didn't already have it. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@30756 a592a061-630c-0410-9148-cb99ea01b6c8
