Patches for few major rgbds releases with current html

[SelvinPL]

Just for some tests I did set of patches for different rgbds version

With build-rgbds.sh like this

#!/bin/bash

set -eu

if [[ "$(which emmake)" == "" ]]; then
    echo "I need emscripten sdk active, see https://emscripten.org/docs/getting_started/downloads.html"
    exit 1
fi

cd rgbds

if ! [ -r ".rgbds_patched" ]; then
    RGBDS_VERSION="$(git describe --tags --always 2>/dev/null)"
    PATCH_FILE="../patches/rgbds${RGBDS_VERSION}.patch"
    echo "${PATCH_FILE}"
    if ! [ -r $PATCH_FILE ]; then
        PATCH_FILE="../patches/rgbds.patch"
    fi
    if [ -r $PATCH_FILE ]; then
        patch -p1 --no-backup-if-mismatch < $PATCH_FILE
        >.rgbds_patched
    fi
fi
