Set timeout for urb.req

Browse Source 
This sets a 1 minute timout on the urb.req xhr object. If no response
is received after one minute, it passes an error to the callback with a
408 status code.

I've also made sure that a 'beat' response resets the dely property back
to 250, instead of maintaining the previous value.

Fixes urbit/talk#21
