Asterisk 1.8 support

Flashphoner has tested with Asterisk 1.6.x and many other VoIP gateways.
There is one specific issue with Asterisk 1.8.x
Asterisk 1.8 uses symbol ":" in SIP call ids. It appears in SIP2Flash calls(incoming calls) via Asterisk 1.8.

Wowza Media Server does not support this symbol as part of stream name. It causes errors.

Solution:

Use custom SipMessageListener, which replaces symbol ":" to unique symbols sequence for incoming SIP messages and replaces unique symbols sequence to symbol ":" for outgoing SIP messages.
So, you should:

Download jar-file with custom SipMessageListener here http://flashphoner.com/downloads/patches/asterisk181-patch.jar and copy this jar-file into WowzaMediaServer/lib dir.
Configure SipMessageListener in the flashphoner.properties file:
```
sip_msg_listener=com.flashphoner.app.ChangeCallIdListener
```
Restart server.
