Add display management script 'srandr.sh'

Added 'srandr.sh' which can utilize a local '~/.display.sh' to read
values as shown in the following:

DisplayConfigs="LVDS1 HDMI1 VGA1"
LVDS1() {
    xrandr --output LVDS1 --auto
}
HDMI1() {
    xrandr --output HDMI1 --auto --above LVDS1
}
VGA1() {
    xrandr --output VGA1  --auto --above LVDS1
}
