Allow feedback to data sources

[charvolant]

If someone thinks that there is an error in a species description, profile, taxonomy etc. there is no obvious feedback mechanism. This is in contrast to occurrence records which can be annotated with queries about identification etc.

We shouldn't be putting annotations on species pages, since they come from expert contributions. However, providing some mechanism for sending queries about taxonomy back to the source might be helpful for people who have something to contribute.

If implemented, there would need to be some mechanism to protect the sources against being inundated by the equivalent of twitter storms.
