TuxSH fe4bb0857b Implement autobooting into homebrew (3DS and DSi modes)
Add config option to autoboot into 3DS and DSi homebrew menu, without
going through Home Menu (nor launching it).

For 3DS homebrew, this requires homebrew built with libctru v2.0.0 or
later (v2.0.0 was released 2.5y ago).

We simulate a "reboot into title" to achieve this. This being said, when
launching stuff like Pokemon US/UM on O3DS, Home Menu reboots into
itself and not the game directly. This will cause Home Menu to crash if
you use this feature and configure it to use a non-default memory layout
(but if you don't, Home Menu will work just fine).
