minor bugfixes
changes to support showing new conds in ignored

Used to be the case that new conditions would not be shown in a section
that had all ignored tests, now they are shown.  This is not super well
tested at this point
quick quit now only if user requests quit

Before quick quit would engage even if user just hit N to all
changes, which took me a bit aback the first time it happened
updating vignette
new condition checking bug fixes

got a bit confused about internal mappings, but now should
properly report when stuff is a new condition in each section
and sub-section
minor doc updates
timer for prompt on quit fixed

was including time at interactive prompt before, now only
looking at test expression evaluation time
