bump the default timeout to 10 minutes as some tasks would otherwise timeout
bump the maxlength of the update action to 0 so we can pass long package lists if necessary
remove trailing whitespaces
rename check-update to check_update to make it easily callable from ruby code
fixed the do_outdated_packages method to also work with long package names
with the old method they would not be listed as they can cause a line break
make check-update also callable as check_update
