Merge branch 'develop'
switch to local svg -> png conversion.

fudge the offsets on the text to work with the version of imagemagick installed on dolph.
this is ugly and annoying, but it seems that every version of imagemagick on every different machine
renders things a little differently.

clearly this isn't a great long-term solution, but at least we can shut off monty now

ideally, we should be using something a little more battle-tested for doing svg -> png conversion
or just switch the graph generation stuff to highcharts or something that has png generation built in
