FP_LIB_TABLE::ROW::SetFullURI() does environment variable substitution up front.

We can now remove a few calls to FP_LIB_TABLE::ExpandSubstitutions( const wxString& aString )
since its being done in above function.

DIALOG_FP_LIB_TABLE now handles table to copy cut copy paste from global to
project and reverse.  Fixed a problem with cursor position management when
switching between tables.
