Resource strings

Resource strings are declared in C++ and loaded by means of a macro.

resourcestring
SIndexError  = 'Index out of bounds: %d';
->
//  "List Index out of bounds: %d"
extern PACKAGE System::ResourceString _SIndexError;
#define Testheader_SIndexError 
   System::LoadResourceString(_SIndexError);

At positions, where resource strings are used, they are now substituted be the according macro.

Exception ( SIndexError )
->
Exception ( Testheader_SIndexError )
