ACP User Administration - fields for non-standard user types

The ACP User Administration has a large number of fields that can be entered for users who have the settings hard-coded into the system (Bots, Anonymous). This falsely leads administrators to believe they can change these settings and it will affect what happens to these users.

In my opinion, the most preferable option, besides rebuilding the User Administration panel, which may be a good option to clean it up, would be to simply hide the fields that cannot be changed for these types of users.

Profile fields, such as location, signature, should be hidden for bots, since their profiles are not viewable, but kept for anonymous users (the administrator may wish to make a note in the signature of guests who post for example).

PMs, emails, and other forms of communication should not be allowed to be received by the guest account, and therefor these settings as well can be removed from administration.
