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).
* Add check for valid symbol library link in annotation code to prevent
crash even if the symbol was not defined correctly. This will assert
in debug builds.
* Fix broken pin comparisons when library symbols have units with alternate
body style defined.
* Remove some macros from LIB_SYMBOL comparison function which made
debugging painful.
* Exit LIB_SYMBOL comparison function as soon as non-equivalent comparison
occurs.
* Fix broken library symbol comparison due to name differences when
checking for existing variants of the library symbol.
