Unmark the visited nodes when searching bindings in class or namespace scopes.

Creator fails to set up the build environment with MSVC 2008 and
Windows Mobile SDK 6.  This is caused by two problems:

1. The toolchain was being searched for in
   C:\Program Files\Microsoft Visual Studio 9.0\VC\VC
   The correct path is
   C:\Program Files\Microsoft Visual Studio 9.0\VC

2. Include statements in mkspecs were not being processed.  All of the
   important variables are set in files included from the
   wincewm60{standard,professional}-msvc2008 mkspecs.

Default background of Rectangle is white anyway.

- If NSX and NSY have quotes for the QT_NAMESPACE case, they need them
  for the non-namespace case too.
- Dumper autotest: Replace hard-coded namespace with compile-time
  dynamic one.

... with an event loop with disabled user input to keep
the GUI alive.

specifically, this will skip the initial stop at _start when using the
terminal and remote adapters.

FIXME: if the attached to program has no relation to the currently
selected run configuration, the qt version config dialog will pop up
rather effectlessly and thus confusingly.

after refactoring the trk adapter startup, the split was not necessary
any more. in fact, it seemed fairly arbitrary at this point.

it is currently unused. do not just remove it, as hjk says he wants to
revive it.

- Turn off initial breakpoint when attaching (terminal) and
  additionally ignore it before the first startup complete
- Refuse to step  the artifical thread created when
  interrupting
- If possible, switch to thread 0 when interupting (do not
  use artificial thread)
- Ignore non-fatal exceptions in dumper calls (stray Startup-
  complete-traps)
- Use right thread for dumper call loading
- Rename windows exception code enumeration
- Turn off modification off watch-data children by setType,
  show empty lists correctly.
- Verbose warnings about inserting invalid watch data.
