[darwin] neovim

[baskerville]

I would be great to have neovim.

I can compile with:

make distclean && LIBTOOL=/opt/pkg/bin/libtool LIBTOOLIZE=/opt/pkg/bin/libtoolize make CMAKE_BUILD_TYPE=Release

pkgsrc carries a trunk version of neovim in the wip tree (which is why it isn't automatically packaged). I'll have a look at packaging a release instead.

It's a PITA a bit because the build tends to fetch dependencies as it goes, that's hardly acceptable, but the main work has been done already.
