Grabber - Remove OnlyGrabOwners check

Line 70:

```
if self.OnlyGrabOwners and (not trace.Entity.GetPlayer or self:GetPlayer() ~= trace.Entity:GetPlayer()) then return false end
```

This check will prevent a player from being able to grab anything other than their own wire component. 

Non-wire components don't have a    :GetPlayer()     function, so this will always return false when trying to grab entities like regular props, even if they belong to the grabber's owner.

Since the    sbox_wire_grabbers_onlyOwnersProps    convar is 1 by default, this will essentially 'break' (in the minds of the players) the wire grabber on every server.

The    wire forcer    , which can be seen as an equivalent tool with the opposite functionality of the grabber, doesn't use an sbox convar and works just fine, which is why I propose this check be removed.
