LIFX - Add support to control the bulbs individually or all three at once

[MatthewKosloski]

It would be cool to control each bulb individually. For instance:

!bulb1 turn the light red
!bulb2 turn the light green
!bulb3 turn the light blue

Or to control all three bulbs at the same time (notice plural bulbs):

!bulbs turn the light purple

Finally got the Philips Hue lights to work as well. It's a bit hacky using IFTTT to do it remotely but it works!. Next step will be to allow individual control as you suggest here.
