Experiment with a ListView style

Browse Source 
I'm trying to make the ListView look like the old owner-drawn
WinForms UI.  The tricky bit is getting long comments and notes to
start in column 5 (label) and extend across multiple columns.

This approach sort of works, though it's currently incomplete, e.g.
the selection highlight style apparently gets dropped.

ListView tweaks from https://stackoverflow.com/a/4472061/294248 . This is
necessary to get long comments and notes to start in the Label column. The
approach feels a little wobbly, but it seems to work.
MSFT GridViewRowPresenter example is promising, but I haven't figured out how to
make long-comment rows follow the same header (maybe manual update in code-behind?).

Item Template Selectors are another possibility, maybe?
