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).
- Add support for saving screen filters color temperature and NTP timezone offset (you still need to go to misc->save config)
- some advanced options moved to "in ini file only"; "patch games" is now enabled by default
- ntp: fix support for UTC+12 to +14
- remove deprecated custom svc 0x2e
