Title: Enh : Graphite separate graph included warn and crit thresholds

I made some change to display separate graph for each metric with warning and critical thresholds included in.
I also include patch from h4wkmoon to exclude non alpha-numerical character for graphite.

I think it possible to improve that by compile regex [^a-zA-Z0-9] and define as an attribute to reuse everywhere we need to replace such characters and by change way to concatenate variable maybe (cf http://www.skymind.com/~ocrow/python_string/ ).
