! Using new method to solve the GET()/TBROWSE()/TBCOLUMN()
symbol problem (these aren't public symbols in Clipper).
The method used is the one already implemented for other
C53 CUI classes.
This allows inheritance, doesn't mess up the class name,
and won't declare above public symbols.
* Moved Xbase++ compatible GET()/TBROWSE()/TBCOLUMN()
functionality into separate classes, all inheriting from
original Harbour classes. This means that Xbase++
compatible methods are only accessible when using the
derived classes. The separation will allow us to
move XPP (and other HB_COMPAT_*) compatible functionality
into a separate libraries in the future, allowing more
freedom to resolve clashing features, symbol names, etc..
* Xbase++ compatible classes are named: xpp_Get(),
xpp_TBrowse(), xpp_TBColumn(). This is a slight
incompatibility compared to Xbase++ and also to
previous Harbour. Technically it seems possible
to give them the names GET()/TBROWSE()/TBCOLUMN(), if
the class is defined in a different file, but let's first
discuss it.
* source/rtl/tgetint.prg
* Using GetNew() instead of Get():New().
; Finally I didn't use '( ... )' to pass parameters in GetNew(),
as it's a tiny bit less efficient with -gc3.
