chomikuj.pl: new module

Requested by irvinetoky.
dl.free.fr (download): return $ERR_LINK_TEMP_UNAVAILABLE on overload error
core.sh: introduce new API replace_all()

Like parse() and parse_all(), you've got replace() (first match) and replace_all() (all matches).

I know this is not good for API compatibility, but I think it is worth doing it now.
Plow* & module sources have been updated.
1fichier (upload): don't use sed but replace_all
dataport.cz (download): fix, upstream updated
uptobox (download): don't use sed but replace_all
chomikuj.pl: fix, folder option bug
