Currently, stargate.use allows players to activate and enter stargates.

It has been suggested that these could be split into:
stargate.use.enter Ability to enter an active stargate (i.e. always on or active by another player)
stargate.use.activateAbility to activate a stargate (i.e. making an always-on sign or using the activator).

For backwards compatibility, stargate.use will continue to be a general node that grants both of the above subnodes.

A small modification:
There will never be a situation where you would want players to be able to activate a gate, but then be unable to enter it, therefore I propose just adding one more permission; stargate.use.enter
