[Serusers] supported methods in SER

[Daniel-Constantin Mierla]

SER can process any SIP request, doesn't matter the type of method. It 
can process the method FOOBAR as long as the whole request is 
well-formatted according to SIP specifications (RFC3261). But this is 
from a SIP proxy point of view -- the methods request a special behavior 
which is specific for SIP clients and SER doesn't do that.
