Hopefully fixed problem where owner is nil.

Fixed issue where the convars were not registered client-side and made the menu actually work now. There are now also notifications to staff when a high rank staff change a setting.

Uncommented a line of code that was used to prevent the notification of attempted propkill from being sent if a person was trying to propkill themselves (forgot to do so before sending the update through as I was using it for testing)

Last Update
Updated GUI and added more options

Full change log:
- Changed up GUI, made it look slightly nicer (still not the best but it looks better than it did)
- Added the following settings to the GUI and addon itself:
* Ability to toggle the color change on attempted prop kill
* Ability to toggle vehicle colliding with players on and off (used to prevent CDM)
- Tidied up some of the code so it's not a entire mess, still kinda a mess but a bit better.

Fixed problem where players were unable to take damage by anything, forgot that OnEntityCreated also contained players so it was an easy fix with Entity:IsPlayer()

- Fixed problems with entities being able to damage people still
- Fixed the messages from repeating so much right away, now it will only display one message per attempt.
- Made it so it will not notify if a player attempted to prop-kill themselves.
- Fixed some of the spaghetti code within it (finally)

Expect a full re-write soon, honestly this is some shit code that I've built on when I made it back when I had just started Lua. So, it really doesn't use some better functions that are to offer.

Known bugs:
- Vehicles are able to kill players if you pin them against a wall since it is instead world damage.

Accidently left out a part of the update, should all be good now.

Added Menu To Toggle Things (lprop_menu in console)

Fixed another error due to my retardedness.

[Anti-Prop Kill] lua/autorun/anti_propkill.lua:58: attempt to call method 'EnableMotion' (a nil value)
1. v - lua/autorun/anti_propkill.lua:58
2. unknown - lua/includes/modules/hook.lua:84

Fix for the following error, due to me being a retard.

[Anti-Prop Kill] lua/autorun/anti_propkill.lua:57: attempt to call method 'InVehicle' (a nil value)
1. v - lua/autorun/anti_propkill.lua:57
2. unknown - lua/includes/modules/hook.lua:84

Let me know if you encounter any other bugs so I can fix them asap. A big update is just around the corner so expect some bugs in the within that and whatever things I mess up beforehand in this version.
