* harbour/include/hbclass.ch
    * most of the rules rewritten
    ! fixed some wrong rules and general cleanup
    + added additional code validation
    ! fixed compilation of more then one class in single file.
      Now it's even possible to declare all classes at beginning of
      single file and then implementing their methods in any order
    ! fixed using static classes and classes
    ! fixed compilation without <ClassName>_ prefix in method names
    + added support for HB_CLS_NO_DECORATION macro which disable
      adding <ClassName>_ prefix to method names - this macro is
      set by default when HB_SHORTNAMES is set.
    + added support for declared parameters validation - it can be
      disabled with HB_CLS_NO_PARAMS_ERR and I had to disable it
      by default due to problems with our preprocessor.
      Ryszard seems that our PP has serious problems with decoding
      directives when there is no space between symbol and some other
      non symbol character. I had to add some workarounds and even
      introduce buggy rules to make it working. Please look at it.
      You can remove #define HB_CLS_NO_PARAMS_ERR from hbclass.ch
      and try to rebuild Harbour core code to see the problem.

  * harbour/include/hboo.ch
  * harbour/source/vm/classes.c
    + added support for new primitive message: HB_OO_MSG_PERFORM

  * harbour/source/rtl/tclass.prg
    - removed <lPersistent> parameter from HBClass messages and
      internals data. Persistent is supported as scope bit and
      separate variable was redundant.
    - removed stripping of () from message names. Here is not a place
      to fix wrong preprocessor rules.

  * harbour/utils/hbtest/rt_class.prg
    * use: METHOD PROCEDURE ... CALSS ...
      instead of: PROCEDURE ... CALSS ...
      The first version is preferable syntax.

  * harbour/source/debug/dbgtmenu.prg
  * harbour/source/rtl/checkbox.prg
    ! fixed some parameters in method declaration - global cleanup
      will have to wait for preprocessor fixes

   Hi all,
   Please make test with current hbclass.ch code.
   I hope that I haven't broken too much things ;-) but I rewrite
   from scratch most rules and it's possible that I missed sth or
   made some stupid typos. Current version is much shorter and should
   be easier to updated. For sure I've intentionally changed one thing.
   CLASSDATA was ignoring SHARED attribute and always created shared
   class variables. Seems that it was long existing typo but the fix
   may interact with already existing code which needs SHARED class
   variables but does not use SHARED clause in CLASSDATA declaration.
   In such case please update it and add missing SHARED.
   Also in the end of CLASS declaration we have:
      [ ; #translate Super( <SuperClassN> ): => ::<SuperClassN>: ] ;
      [ ; #translate Super( <SuperClass1> ): => ::<SuperClass1>: ] ;
      [ ; #translate Super(): => ::<SuperClass1>: ] ;
      [ ; #translate Super: => ::<SuperClass1>: ] ;
      [ ; #translate ::Super : => ::<SuperClass1>: ]
   These rules introduce very serious bug - they are breaking supercasting
   in code which makes sth like:
      ::super:super:super:msg
   or in any other code which sends SUPER message to some other class
   objects. I will have to remove them. At least the last three ones.
   There were some other things I wanted to write about but it's too late
   and I'm to tired - sorry. If you will have any question please ask. if
   you will notice some problems with current rules please inform me.
