Implement aoc:u and support loading AddOnContent (#1221)

* Initial rebased AddOnContent support

* Fix bounds calculation
* Use existing GameCard in VFS per Xpl0itR's suggestion
+ Add dummy IPurchaseEventManager per AcK's suggestion

* Support multiple containers

* Add option to selectively disable addons

* Import tickets from AOC FS

* Load all nsps in base directory automatically

* Revert LoadNsp renaming

Removes conflicts with Mods PR. Not much is lost, old names were fine.

* Address AcK's comments

* Address Thog's comments

Dispose opened nsp files
Fix potential bug by clearing metadata on load
