fix #48
This should be compliant with rfc7232 except it does not implement If-Match and If-Unmodified-Since as they make sense mostly for state-changing methods, to not overwrite modifications made by other user-agents.

LGTM. Before I merge, is there a possibility that a request contains both If-None-Match and If-Modified-Since, and is the behaviour specified in that case?

It is possible, and is even usually the case. In this situation If-None-Match takes precedence and If-Modified-Since is ignored (as per 6.Precedence from rfc7232). The rational being that etag based matching is more accurate, it has no issue with sub-second precision for instance (in case of very fast updates)
