Clean up project settings.

- Create single platform config named x86 and have all projects target x86.
- Remove Release config (broken anyway).
- For the Debug config, ensure TRACE and DEBUG constants are set and unsafe code is allowed for all projects (same as the makefile).
- Warn level 4 and optimizations off were removed from the config automatically by VS (it assumes these values by default, and these match the makefile).
- The CrashDialog project can reuse the icon from the Game project as long as the path is set correctly.
- Fix TS project so it builds (I know it's going but its annoying that the project must be unloaded).
