nvim: Add custom spellcheck toggle with user events

Browse source 
Added a user command `SpellTogle` which toggles on or off spellchecking
in the current buffer. Can be invoked like that, or with one or multiple
language to spellcheck (e.g. `SpellToggle en_us en_gb`). Can also be
invoked with a bang to always enable instead of toggling.

Publishes a user event called `SpellEnable` or `SpellDisable` depending
on the aciton which autocommands can listen for.
