Title: Include dependency paths when calculating mtime

The mtime of assets do not take into account the mtime of assets dependencies added using `depend_on` or `depend_on_asset`. Each Sass integration uses one of the two methods (Sass::Rails, Sprockets::Sass, Sprockets::SassImporter) to get `@import` working correctly - so most CSS files precompiled with Sprockets have an incorrect mtime.
