Log:
[HIVEBCD]: Fix wrong element type for application device element.
[BOOTMGR]: Implement boot sequence population. We correctly detect our winload.efi entry
in the BCD hive.
[BOOTMGR]: Document more application entry flags.
[BOOTLIB]: Document and implement BCD object description parsing. Based off BCD Reference
Guide / Geoff Chappel's website.
[BOOTLIB]: Add support for appending a boot option to an entry.
