Added additional warnings to flag common gotchas:

* Warn when ethernet bridging that the IP address of the
  bridge adapter is probably not the same address that
  the LAN adapter was set to previously.

* When running as a server, warn if the LAN network address is
  the all-popular 192.168.[0|1].x, since this condition commonly
  leads to subnet conflicts down the road.

* Primarily on the client, check for subnet conflicts between
  the local LAN and the VPN subnet.

Added a 'netmask' parameter to get_default_gateway, to return
the netmask of the adapter containing the default gateway.
Only implemented on Windows so far.  Other platforms will
return 255.255.255.0.  Currently the netmask information is
only used to warn about subnet conflicts.
