Ignored SDP fields

[alexeysimak@xxxxxxxxx (Alexey Simak)]

Hello,

Current version pjproject-2.0.1 ignores next SDP fields during parsing:

i=* (session information)
u=* (URI of description)
e=* (email address)
p=* (phone number)
r=* (repeat times)
z=* (time zone adjustments)
k=* (encryption key)

Are you going to add support for this fields? 
If yes, I can handle this task.

Thanks,
Alexey Simak
