This removes the hack that enables directly booting from WADs without installing them first for the following reasons: 1. It makes the NAND content handling much more complicated than what it should be and makes future changes like permissions or booting NAND titles without a WAD more annoying to implement. Because of this hack, we needed an extra level of abstraction (NANDContent*) which has to read tons of things from the NAND, even most of the time it's useless. This in turn forces us to have caching, which is known to break titles and requires manual cache invalidations. Annoying and error prone. 2. It prevents the WAD boot code from being easily accurate. With this change, we can simply reuse the existing launch code, and ask IOS to launch the title from the NAND. 3. The hack did not work that well since it did not cover a lot of ES commands. And it works even less since the ES accuracy fixes. This results in Dolphin returning inconsistent results: a lot of the ES "DI" commands will just fail because the active title is not installed on the NAND. uid.sys is not changed, etc. And I'm not even talking about FS stuff -- where this would still totally fail, unless we add even more unnecessary hacks. This is not just theoretical -- the system menu and the Wii Shop are known to behave strangely because the hack damages the NAND structure, and we've already had several users report issues. This commit makes it so WADs are always installed prior to launching. A future commit will remove any code that was there only for the hack.
