Bug fix #57: Fix incorrect handling of InputOnly windows

Browse source 
- Stop rendering InputOnly windows. In the past I've misunderstood the
  whole thing, I guess, sorry. Thanks to garfilth and funeral1988 for
  reporting and providing valuable information.

- Fix a possible segfault in DDEBUG_EVENTS.

- Add "dbe" as a configuration file option.

- Attempt to slightly reduce the rendering delay after VSync in non-DBE
  mode. I don't think, however, that this would be greatly helpful for
  the tearing issue.
