Add a0 support (stop sysinfo) and other things *READ BEFORE MERGING*

[erew70]

What has changed:

• add a0 support to stop the a0 service (block sysinfo playreports)
• remove home button led flash (i am pretty sure it has been rewritten since the old code is based off an old libnx apibut if you would like to add it back in you can)
• update gamepad to latest libnx api
• Updated Readme.md (you can revert back to the old one if you like you dont have to change that

Notes:
Everything has been tested and working
I would also recommend modifying the save files on the sd card too (SYSTEM partition) it is not in the code btw
