Feature request: xbacklight symlink support

[nick87720z]

What if light supported xbacklight with all its options, like in acpilight (including floating point options -getf, -setf) if started via symlinks /usr/bin/xbacklight -> light?

I'm not proposing creating wrapper script, because e.g. acpilight's xbacklight is also script. I have tint2 executor to control backlight with scroll, in my case it's touchpad scroll. Rate of event with touchpad scroll is insane, and with xbacklight python script from acpilight it creates immence load, while with light it's... light.

Not that I'm delivering it to anyone - just to know, if this ok to be maintained later. I would do it as just alternative args parsing function, to be chosen depending on executable name.
