ie, when viewing a "current" period (the current day/week/month/quarter/year),
it will be moved to enclose the current date, if needed, whenever the system date changes.
accounts and register screens can now switch between "historical"
(default) and "period" modes
title header wording is clearer
quick help footer now indicates historical/period and tree/flat modes,
saving space in the title
help screen is more explanatory
the enter key has been reserved for later and is no longer an alias
for right/l
