update ui.quiet/verbose/debug/interactive every time the config changes - ui.quiet/verbose/debug/interactive become just a cache of the ui.cdata settings - the quiet, verbose, debug and interactive options from the [ui] section from .hg/hgrc files are respected for commands that open the repo - setting ui.quiet/verbose/debug/interactive with --config works - the command line options always override the hgrc settings - previously it wasn't possible to override a [ui] debug = True. --debug still takes precedence over --quiet and --verbose.
