- updated wl-broadcom script to work with latest wl
  this is untested but the old one doesn't work and 
  i have no time to test next days

- removed output noise from ifup, used mprint instead of echo

- updated manual stuff, from now manual doesn't configure iface
  but sets it up or down

- removed bridge shutdown if bridge init fails
  not to 100 percent complete initialized bridge is better than
  having no network, the normal user doesn't have serial access
