rc spell: Allow storing a language in an option

Browse Source 
This commit adds a `spell_lang` option that will be used by the
`spell` command when no language is passed to it directly.

Setting a buffer/window local option allows using `:spell` seamlessly
across several buffers, written in different languages.
