Cumulative changes from main branch (trunk).

With these changes ATF version is upgraded to v3.10.6.0

New Features:
+ Curve Editor:
   - More fine grained control over paste operation using paste options dialog box.
   - Skinning can be applied to most of the curve editor properties.
+	Support xs:all  element
+	Made AnnotatingCommands more general purpose see pull SonyWWS#55

Bug fixes:
+ Schema loader didn’t handle  <xs:all>
+ Min and max occurs for elements in xs:sequence wasn’t correctly handled.
+ Null reference exception fix in ControlHostService.  In some cases during application shutdown a null reference exception was thrown by ControlHostService.
+ PropertyGridView's Pick() could return wrong object see  pull SonyWWS#54
+ Location of the current x line was incorrectly constraint.
+ Fixed a long standing minor auto fit bug.
+ DomTreeEditor:  After first save, document wasn't get dirty when it is modified.
+ DomTreeEditor:  File changed confirmation dialog didn’t display when user opened new document while the existing one is dirty.
+ SkinService:  Forms were tracked twice in WindowCreated event handler.
