Added Twilightcyanide ColorScheme + fixed label of Monocyanide ColorScheme.

[Twilightcyanide ColorScheme](https://github.com/Centril/sublime-monocyanide-colorscheme) is [Cyanide](https://github.com/lefoy/cyanide-theme)-ified [Predawn Twilight](https://github.com/jrnewell/predawn-twilight-theme): darker background & lighter foregrounds.

I've also fixed the label of [Monocyanide ColorScheme](https://github.com/Centril/sublime-monocyanide-colorscheme) to fit what others are using.
