Add light mode (or non colored text)

I use solarized light and the pod name is unreadable. Related to #11

Damn, that's a bummer. Would setting environment variables and/or flags be acceptable as a quick-fix?

alias kail='KAIL_BG_THEME=light $GOPATH/bin/kail '

Yep, I have no problems using a flag or env variable.

I'm having the same issue on macOS using kail. Using alias kail='KAIL_BG_THEME=light /usr/local/bin/kail ' or export KAIL_BG_THEME=light doesn't work.

Output of kail version (installed using brew):

0.15.0 (58d7816d3d93cccb1903603512e40919a843c760)
