postcss-icss-selectors

This project is combination of postcss-modules-local-by-default and postcss-modules-scope with separated selectors scoping funtionality.
Here a few notable changes

• keyframes scoping implemented now in postcss-icss-keyframes
• checking consistency and pure mode was removed. Linting is more appreciated here
• .class:local.class not allowed anymore in favour of .class:local(.class) or .class :local .class
• url scoping is removed. Much better to control all paths with loader functionality via postcss-icss-url
• :global { .selector {} } behavior was removed
