Remove unecessary binary components.
Clean up olsrd.conf.
Handle state changes while LinksActivity is paused

In the case where the network state changes while
LinksActivity is paused, it would not properly
update its monitor thread state. This meant that
ClientData objects would linger even when the network
disconnected and would not appear when the network
connected.
Improve route handling

1. Do not accept 0.0.0.0/0 routes without a
specific next hop. In other words, do not
accept link routes.

2. Clear out existing routes before starting
olsrd. This should not mess with the user's
configuration because these routes are not
configurable by the user through the normal
UI.
