after-v.0.0.9

These were changed after version .0.9. If you like it the way it was, you may try this lua
code:

```
local n = require('neosolarized').setup({
  comment_italics = true,
  background_set = true, -- set this to false if you use transparency
})
n.Groups.new("@parameter", n.colors.base0)
n.Groups.new("@variable", n.colors.blue)
n.Groups.new("Special", colors.red)
n.Groups.new("Preproc", colors.orange)
-- n.Group.link('WarningMsg', n.groups.Comment) -- my personal preference, but this hasn't changed

```
