Add whether Crowd is present to the System Info page

We have had a few support cases and live chats recently where the customer has said that they are using Active Directory. We have assumed that they would tell us if they were also using Crowd, so we assumed that they were using the "default" LDAP support. It wasn't until much later that we found out that the customer was also using Crowd. Knowing this earlier would have saved some time and avoided confusion, so...

Could we add some info to the System Info page telling us that Crowd is present? Simply "Crowd is here' would help, although I imagine there are some useful Crowd configuration parameters that you could display as well.
