sth is deprecated

[vagusX]

postcss was renewed recently - https://github.com/postcss/postcss/releases/tag/5.0.9
and we see the following:

Container#eachRule is deprecated. Use Container#walkRules instead.
Container#eachDecl is deprecated. Use Container#walkDecls instead.
Node#before is deprecated. Use Node#raws.before

So, can u update it?
