Pulling in new events

It would be helpful to have a way to update each workshop from this list:

https://aclanthology.coli.uni-saarland.de/events/ws-2018

We could do it manually but it's also a bit difficult to map each of these to the short codes (e.g., bea).

The way I envisioned it was to have a way to update the whole acl anthology bib index. Because bibsearch stores which bibfiles it already has downloaded, doing bibsearch add bib://acl will only download conferences/workshops that have been added since the last (local) update.

This script generates the listing for the ACL anthology, but assumes a local mirror of the events/ directory of the anthology. Ideally we would generate the acl listing from the xmls in the athology's repo, but a quick look at the files did not show a clear way on how to accomplish this.

Another thought on this is to reorganize the catalogs. One difficult in adding the workshops is in mapping the entries here:

https://aclanthology.coli.uni-saarland.de/events/ws-2018

to the workshop IDs used in acl.yml. For example, what identifier should be used for The second workshop on subword character level models? The answer is that we shouldn't have to choose. Maybe your solution of downloading the entire anthology is best, but I think that will be time-consuming.

This is another good resource we might update from:
