Could not delete wrong source
+example
Greenpeace wants to change the source linked to a value on their project, but weren't able to. http://wikirate.org/Benetton_Group_Spa?view=new_metric_value&project=Detox_Catwalk_2015
Henry was nice enough to delete the unwanted source for them, but considering that this might be a recurrent issue, maybe granting access to users to be able to edit/delete sources linked to values is needed.

looking into this. we think it's just a matter of fixing permissions settings and adding interface; the api already handles this.
We believe we've fixed the permissions issue. For now, if you need to delete a source, just add "/delete" to the beginning of the source url, and it should work. We've added pivotal tracker stories to handle the interface to make this less weird.
