ui: move configlist parser to config.py The list parser is complex and reusable without ui. Let's move it to config.py. This allows us to parse a list from a "pure" config object without going through ui. Like, we can make "_trustusers" calculated from raw configs, instead of making sure it's synchronized by calling "fixconfig"s.
