Updating AMQP plugin

[Flavio Campana]

Hi,

i'm trying to update an amqp plugin (the one listed on gatling site) to currente version of gatling and scala.

https://github.com/SilverXXX/gatling-amqp

While most changes were easy and straightforward, like 

      val now = TimeHelper.nowMillis //old

      val now = ClockSingleton.nowMillis  //new

I found a strange bug, maybe a preexisting one:

    val name = "AmqpConsumerCorrelation"  //

    val name = genName("AmqpConsumerCorrelation") //new

With the old line i always got error on consume, i used genName to solve it.

Is it correct?

Thanks
