First implementation of packet-openwire.c

Build Information:
Here is a dissector for ActiveMQ OpenWire protocol.

A few words about the protocol : 
OpenWire has two wire formats :
- "loose" : more verbose, less CPU-intensive, less network-intensive (1-pass)
- "tight" : more compact, more CPU-intensive, more network-intensive (2-pass)
This dissector only supports the "loose" syntax, which is not the default.
This dissector only supports version 6 of the protocol.
It can be changed on the broker in the activemq.xml file by specifying
"tightEncodingEnabled=false" :

There is a sample capture uploaded on the Wiki :
It contains 3 variants of the protocol : 
1. "loose" and "nocache"
2. "loose" and "cache"
3. "tight" and "cache" 

I performed 3000 runs of fuzz testing with success.

Patch was tested against Wireshark 1.6.5 and 1.6.6.

Please review.
