Enabling the Sitecore license ID on the logon screen for Sitecore 8

Since Sitecore 8, for some reason, it seems like the license ID is considered something confidential.

Now, it is no longer rendered by default - however, if you want to have it back at the login screen, change the following setting to false in an include file: Login.DisableLicenseInfo

Once you have done that, it can be accessed from the login screen again.
