fix cert dir specification when tls is not configured (note, you probably need to move your certs for wss after this commit)

trying to get mozilla to work using sipml5, got stun/dtls/rtp flowing and its dead silent.  c'mon guys... why do you have to do everything differently?????

make opus work, omfg .. serious???  you need to always advertise it as stereo using the standard way then specify it in the fmtp insread just to complicate things.... that's not cool =/

force the version header in the rtp packet to 2 when pulling data out of the jitter buffer because when you get a stun packet it will still be 0 from last time
