SDL Input Joystick for GZDoom v4.12.2 for RetroPie

SDL Input Joystick for LZDoom (SIJL) has moved to GZDoom
SIJL will retain it's Name + Older LZDoom Branches for now

Add support for SDL Input from Joystick in Menus eliminating the need for a Keyboard.
Additionally includes Pre-Configured Joypad Mappings + Raspberry Pi specific Tweaks
NOTE: You must COMPLIE GZDOOM yourself, the Menu Script just helps you load the DIFFs

This isn't really new, it was started a long time ago under this topic:
Zdoom and Gampad Fully Working in MENU with NO KEYBOARD
This is just Updated [rpi_fixes.diff] and slightly tweaked [gzdoom.sh] for gzdoom

1- Use [gzdoom-sijl.sh] Menu driven Script to assist with [sh/diff] files placement.
