[IMP] web: keep supporting old cids syntax in url

Commit [1] changed the separator of cids in the url to make it
better looking, by using a character that doesn't need to be
encoded (namely, "-" instead of ","). However, by doing so, urls
still using the former separator couldn't be correctly parsed
anymore. This commit adds a small backward compatibility layer,
s.t. links in emails for instance keep working as before.
