TermCursorNC missing

[rajive]

This is working great! Thanks! However just ran into one issue: the TermCursorNC highlight group is missing (using on nvim 0.5 stable):

:hi TermCursorNC
TermCursorNC   xxx cleared

It is defined in vim-solarized8 theme.

For rationale on why TermCursorNC is needed, please see http://vimcasts.org/episodes/neovim-terminal-paste/

Thanks!
