--download-new-posts default always sets flag

Currently, -n is default 24 and it will always using with -f even you input url.

using cmd
fantiadl.py -c XXX https://fantia.jp/posts/XXX

Actually running
fantiadl.py -c XXX -n 24 -f

========================================

using cmd
fantiadl.py -c XXX https://fantia.jp/posts/XXX -n 1

Actually running
fantiadl.py -c XXX https://fantia.jp/posts/XXX -n 1

From I tested.
url only works when -n 1
or it will perform -f and ignore the url.
