Misordered entries in struct callback callbacks[]

[Yotam Rubin]

Greetings,

	It appears as if Arguslookup_pcap_callback() cannot return a pointer
to the raw packet handling routine. The loop is terminated whenever it 
encounters a NULL callback.function. Now take a look at the definition of
struct callback callbacks[] in server/ArgusSource.h, the handler for 
DLT_NULL is being defined before the handler for DLT_RAW, thus making 
the DLT_RAW entry unreachable by Arguslookup_pcap_callback().
Switching the lines should remedy the problem.
