Ultisnip support

[rjshrjndrn]

Hi,
first of all thank you for this awesome plugin. Just a request, when I was using coc used to get apreview for ultisnips.
Now I'm using deoplete, and for floating windows, float-preview is suggested.
But ultisnips are not providing any snippets.

Hi,

This plugin applies to info field of completion item. You could try sending a PR to https://github.com/SirVer/ultisnips/blame/master/rplugin/python3/deoplete/sources/ultisnips.py to add the info field.
