Admin Log Tweaks

-Wire cut logs are now accessed via the Investigate verb, instead of popping up in the admin chat log.
-Wizard Fireball explosions no longer create admin chat log messages either.

-Adding and removing Player Notes is now logged.
-The note that is added automatically to people who get banned, now displays the duration of ban.
The auto-notes which are added when a ban is applied won't cause logs.
Removes the "Remove All Notes" options from Player Notes. Ckeys are cleared from the list automatically when the last of their notes are erased.
