Custom event to evaluate scripts on a connector

[molant]

Initial comment: #494 (comment)

Right now we are telling developers to use traverse::end to evaluate their scripts. The problem is that with the changes in #494 with jsdom we could actually evaluate at the beginning instead of waiting at the end to save a few seconds. That is not the case with chrome where we will be interfering with the page.

The proposal is to create a new event canevaluate (or similar) that will be fired by the connectors when it is best for them to evaluate. jsdom will fire it sooner than chrome in this case.

What do you think @sonarwhal/contributors ?
