Uniqueid is converted to float with precision-problems

It seems like adhearsion converts the uniqueid of an asterisk call to a float, which really breaks the whole unique-id purpose. When you fetch the remote id via manager-events, you get a string (as expected). That string differs from the unique-id of the same call in dialplan..

INFO agi: Handling call with variables { ... :uniqueid=>1173223225.10309 ...}
INFO events: #<Adhearsion::VoIP::Asterisk::Manager::ManagerInterfaceEvent ... "Uniqueid"=>"1173223225.103088" ...

This is the same call, and presumably they should have the same uniqueid. I think unique-id should always be treated as a string (over the whole system) as it might even be prepended by a string (by asterisk) if running several asterisk-instances on one server.

And with this rounding you get the chance of duplicate unique-ids which would be very bad when using it to identify calls in db etc.
