Updates to SIPVicious tools

In the past two days I've been busy working on updates for SIPVicious tools:

• Scanning a large number of hosts does not take long for to start anymore
• Fixed a few bugs / unhandled exceptions
• we're doing 160 hosts per second now :)
• updated user documentation for svmap
• added some switches to svmap:
• Verbose. The mode you add of these, the more debug information you get. -vvv for ub3r super debug info.
• Binding ip -b. This allows you to specify an IP address to bind to. By default it binds to all IP addresses.
• External IP -x. Allows you to specify your external IP address. Use this when you're behind NAT and / or have multiple network interfaces on the host.
  

Currently SIPVicious tools only support UDP. I hope to integrate TCP and TLS later on though not too soon. Any feedback is welcome. If you want to take a look .. look no further than the svn repository ;-)
