[PEAK] peak launch

[alexander smishlajev]

hello!

on windows, 'peak launch' command does not work as expected because of
the socket implementation:

     >>> import socket
     >>> socket.getfqdn('127.0.0.1')
     'alex'

so i get "Connection refused" error in my browser, and have to edit the
url before i can see anything.

even if i explicitely set peak.tools.server.url to localhost in
peak.ini, the browser is run on calculated (broken) url instead of the
address specified in peak.ini.

also, i would like 'peak serve' and 'peak launch' to print their base
url on start if that is possible.

best wishes,
alex.
