merge
change some hardcoded Factory to $proj
replace update_supplements.sh with libsolv script
allow to override project
init osc dir and fail on errors
honor $proj, don't use /tmp
all other cases don't specify the system
use NO_BSMIRROR to avoid writing to the cache dir
move both osc ci to the end

easier to comment for testing :)
move to subdir
move generated files
remove options file
