Using a boolean argument just leads to a lot of trailing booleans in the
function calls and is not user friendly. Instead, introduce PostAction()
to send an action that runs after the coroutine (equivalent to passing
false or the default argument), and leave RunAction as the immediate
execution function.
A sheetpath is required to correctly resolve text variables.
Depending on currentSheet is rife with bugs.
There are many places where we do *not* want to be prepending
field names to the field values, such as netlisting,
building PDF hypertext menus, etc.
Also, Find/Replace needs to work on unresolved text, as
that's what we're going to display (and if replace nuked
your variable references you wouldn't be happy).
Some of these are due to moving to wxWidgets 3.2, but I'm not sure
all of them are. In particular, the need for CallAfter() in the
search pane's selection handler is probably just a wxWidgets bug on
Mac (the control lies about the current selection inside the event
handler).
Also sets better column widths in the search pane.
