Log:
- Add dumping boot drivers list, remove unneded comment
- Implement WinLdrScanRegistry() (based on freeldr's already existing implementation)
which searches for boot-loading drivers
- Implement WinLdrAddDriverToList() - it correctly fills an entry in the BootDriversList
in LoaderParameterBlock
