Add spell-checking to snippet comments

[RomFouq]

Expected behavior: Misspelled words should be highlighted in snippet file comments.

Actual behavior: They aren't.

Steps to reproduce Write a comment in a snippet definition file, with some misspelled words.

Adding spell-checking It seems that adding the @Spell syntax group to snipComment and snipmateComment (not tested for this syntax) is enough.

Replacing contains=snipTODO with contains=snipTODO,@Spell in https://github.com/SirVer/ultisnips/blob/master/syntax/snippets.vim#L34 fixes the issue, and comments are spell-checked.

I think adding contains=@Spell in https://github.com/SirVer/ultisnips/blob/master/syntax/snippets_snipmate.vim#L21 should work too, if needed.

Thanks for this plugin, for which it is a breeze to write snippets! :+1:
