This also fixes a bug where the deprecation flags would not always be respected when using embedded Sass, as ImportCaches could be created with an unwrapped logger, meaning any parse-time deprecation warnings (e.g. @import) couldn't be controlled. ImportCache now wraps the logger it gets in a DeprecationProcessingLogger to fix this.
