Fix comment parsing to support multiple comments

This fixes MyIntervals#173.

Because of an eager consumption of whitespace, the rule and csslist
parsing would swallow a trailing comment, meaning the comment for the
next rule/list would be affected. This patch addresses this by not
consuming whitespace after a rule/list.
