Fix a bunch more issues with sheetpaths and allowExtraText.

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).
