Checked arguments inside purge include and exclude lists

An include or exclude list that ended with a comma took the next token
as a list value whatever it was. The radius, world and action parsers
still read that token, so /co purge t:30d e:zombie, a:foo skipped the
kill-only action check and ran without an action restriction, and any
unknown key after a trailing comma skipped the unsupported argument
check. A list now continues only with plain or minecraft: namespaced
values; any other key ends the list and is checked as an argument.
