docs: mention custom splash script in changelog ...

Also, bring commit count for the fusee_cpp PR to a nice point before merging.

utils: add script for inserting custom image into package3

ams: docs/build update

fusee: accept spaces inside ini values (we still left/right strip)

fusee: add package3 magic

fusee: accept ini files without empty line at end

fusee: attempt reboot to self if possible, better abort/fatal handlers

stratosphere: remove 0.19.0 update cleanup logic.

fusee: remove TODO comments in buildscript

fusee: tactically don't trash PLLA1, fixes audio corruption on boot

patches: nogc patches now embedded in fusee rather than being .ips

config: BCT.ini no longer exists

ams-1.0.0: bump version number well ahead of time

fusee_cpp: rename source dir to fusee

fusee: delete fusee (this will break build temporarily)

ams-1.0.0: meso no longer optional, remove conditional logic

fusee_cpp: improve/fix file-based emummc

fusee: fix sd card size detection for emummc

fusee_cpp: improved relocation logic

fusee_cpp: various fixes, unpatched erista boots now

fusee_cpp: implement package2 rebuild/kip patching

fusee_cpp: fix mariko mtc (mariko now gets as far as erista)

fusee_cpp: validate mtc overlay before jumping to it. ...

mtc will jump back to us, so we need a compatible binary.

This also makes some changes to our layout to minimize the likelihood of
an incompatible mtc binary (I made some arbitrary .text/.rodata/.rwdata changes)
and saw identical mtc binaries, so hopefully this all works out.

fusee_cpp: emummc implies decompressed text segment

fusee_cpp: implement ips patching of kips
