wip: for color and line editing upgrade/improvements.  Needs work on tests & some cleanup,
review, process ck.  Probably already largely tested w/ breakpoints on changes.
Also in Controller ~978 added feature to change companion entity/group names at the
same time, tested it w/ breakpoints, but needs proc.
Bugfixes & enhancements:
- fix crash when moving entry in grp beyond what's displayed
- in that same scenario, fix display to scroll enough to include the moved item
- "value too long for type": make it allow editing of the too-long value
- improve convenience of menu options: change what quickmenu 3/edit does, add directly to subgrp option
