* Update of documentation re MDMessageCmd for new "installed" call.

Define a program to be called when something happened concerning a managed domain. The program is given the reason and the name of the MD as arguments. The program should return 0 to indicate that the message has been handled successfully. The reasons for which it may be called are:
* `renewed`: the certificate for the managed domain has been renewed successfully. Should the command return != 0 for this reason, it will be called repeatedly until it does.
+ * `installed`: the certificate for the managed domain has been installed at server startup/reload and is now used. Different to all other messages, this one is invoked while the server is still root and has according privileges. (Hint: you may use this
+ to copy a certificate+key to another application's preferred location/format.)
* `expiring`: will warn about an expiring domain that could not be renewed (or where renewal is not performed by `mod_md` itself). See `MDWarnWindow` on how to configure its timing.
* `errored`: errors were encountered during certificate renewal. `mod_md` will continue trying.
* `ocsp-renewed`: when MDStapling is enabled for a domain, this indicates that an OCSP response from the Certificate Authority has been updated successfully.
