ZTS fixes

Namespace patch. Big changes:
1. Nested classes are gone.
2. New syntax for namespaces:

Namespace patch. Big changes:
1. Nested classes are gone.
2. New syntax for namespaces:
namespace foo {
class X { ... }
function bar { ... }

For now, namespaces are case insensitive, just like classes.
Also, there can be no global class and namespace with the same name
(to avoid ambiguities in :: resolution).

Rework static class properties - now supports access restrictions

Core rearrangements - move Zend Objects specific code to their

- Added some missing CVS $Id$ tags, headers and footers.
