lib-settings: Allow using comma as deflist separator. This means that when adding new block {}s via e.g. userdb or post-login script, the block names can now be set with block=a,b,c instead of "block=a b c". This is beneficial with e.g. passwd-file or userdb default_fields where spaces are used to separate parameters entirely.
