[chronojump/importer-encoder-files: 4/4] chronojump-importer: imports the Encoder files (renaming the file and adjusting the database).



commit 12cf9cd9121ad73a8b01b1b00e4c6f8397c6f6d1

    chronojump-importer: imports the Encoder files (renaming the file and adjusting the database).
    
    There is a new argument for the chronojump-importer: it needs to know
    where the encoder files are. It cannot find them from the database path
    because Chronojump copies and updates the database before importing it.
    
    It also decides which Persons to import based on PersonSession77 table.
    It is much shorter.
