Added transition to the guard call

[willemo]

I've added the current transition to the guard call, so the guard can be aware of the transition being applied. You can then just define your guard like this: function($stateMachine, $transition).

+1 My team would also love if this feature were merged. It allows our Transition guard callbacks to be made aware of runtime $parameters such as currently logged in user object or the result of other permission checks. For example, if the currently logged in user does not have a specific Role/Permission (boolean result injected via $parameter) the guard callback returns false.

@yohang What can we do to have this feature added? It does not break BC.

@yohang any plans on adding this ?
