for some reason the GUI pilot server for testing doesn't go to the end
of the input field for edits, so the things that backspaced over old
values need an extra 'end' keypress now. I didn't look into why this is,
because it's fine in the actual GUI regardless

this tree UI allows for viewing and basic editing of a configuration
section from a board. it does a decent job of displaying most of the
settings, and editing is equally convenient, as in it tries to handle
enums correctly, but doesn't validate pins or handle long binary strings
well.
saving is done in place --- if a config/storage section was opened, a
config section (no padding) is what results. if a whole board was
opened, the whole binary is rewritten with the new offset config
section. this way, a whole board dump can be changed in place, or a new
config can be made for use in e.g. concatenate to build an image
many enhancements to come over time
