nvim: Move base16 functionality to plugin config

Moved loading and setting up file watching to the loading of the plugin itself.
Will make it a little more self-contained and not crash or complain if we are
missing the plugin.

HACK
At the same time, reverted back to pinned base16 commit since the new one did
not work again. Gotta figure it out at some point but no time now.
