List managers at beginning of rake task

[delitescere]

It would be great to see where the managers are, so it's easier to shut them down if there's a stray one. Example new output:

> rake specjour
Waiting for managers
Managers found: 2 (thehostname.local:57406, thehostname.local:57407)
 Workers found: 16

Here's a patch that might rock it:

diff --git a/lib/specjour/dispatcher.rb b/lib/specjour/dispatcher.rb

       @printer ||= Printer.start(all_specs)
     end

Thanks for the patch, I'll try to get it in soon.
