Doesn't load properly when using true color in Neovim

[lithammer]

So true color support recently landed in Neovim neovim/neovim#2198. But it seems like hybrid gets a bit confused by this (see screenshot).

It get solved by reloading the colorscheme though, or defining the gui* values.

I guess there's two ways to approach this:

• Treat $NVIM_TUI_ENABLE_TRUE_COLOR && has("nvim") as has("gui_running").
• Always define both "vmodes" (gui and cterm).
