re-work multi --styles-file

--styles-file change to append str
--styles-file is [] then defaults to [styles.csv]

--styles-file accepts paths or paths with wildcard "*"

the first `--styles-file` entry is use as the default styles file path
if filename a wildcard then the first matching file is used
if no match is found, create a new "styles.csv" in the same dir as the first path

when saving a new style it will be save in the default styles file
when saving a existing style, it will be saved to file it belongs to

order of the styles files in the styles dropdown can be controlled to a certain degree by the order of --styles-file
