Smartens the cache freshness checking, and adds checksums of constituent-directory last-mod-dates to the footprint info list. Also inserts the dataPtrs into the list at the same time as the text to keep wxWidgets from measuring the width of the text twice (yes, really). And converts the list to default- column widths in case the wxWidgets patch is present to greatly speed list creation (by not measuring all that text). On my machine drops the first-load time from 4s to 2.5s and the subsequent-load times from 2.5s to < 1s. With the wxWidgets patch subsequent-loads become near-instantaneous.
