Safety on/off direct commands and notifying sounds

This change creates two new commands for the client: "safetyon" and
"safetyoff"
These can be bound to hotkeys aliases or typed.

The effect is obvious.  "safetyon" turns the player's safety on while
"safetyoff" turns it off.

I also added a subtle safetyon message sound "click" and a more
aggressive safetyoff noise.

The reason for this change is that safety management is tedious during
pvp.  Players now have access to multiple characters and can
inadventently turn their innocent characters into outlaws or murderers.
The notification sounds provide instant feedback upon logging in as to
the state of the safety and the aliases allow players to quickly disable
or enable the safety without having to fight the interface.

I am not sure where to put the sound files to be committed.  I have
placed them in the run\localclient\resource directory as that is the
place that makes the most sense to me.

I adjusted my editor to convert "tabs" to "4 spaces"

Seems to have fixed the indent issue I was having.
Adjusted number of spaces to 3 from 4

Adjusted the number of spaces from the bracket to the Send command to be
3 instead of 4.  This matches all other code I see in the user.kod file.
I know the request was to change the identation from 3 to 2 but I don't
see "3" anywhere, I see "4."  [pic uploaded]
