Fixed my own issue #855

Instead of spitting errors, it does nothing with the clipboard if the
string is empty.

Tested on my server. No side effects noticed.

    Fixed error with scars
More reliable arrest SetPos, references #405
Merge branch 'master' of github.com:FPtje/DarkRP
Removed IP code
Fixed another scars issue
Fixed locking with SCARs
You can now make SCars purchasable. Example:
timer.Simple(0, function()
AddCustomVehicle('DeLorean', 'models/delorean_prop.mdl', 200, nil, function(ply) return ply:Nick() == 'Marty McFly' end)
end)
Note: the timer is mandatory because SCars load after DarkRP
Fixed #858. W/e
