[SR-Users] rtpengine module dependencies

[Juha Heinanen]

rtpengine module README tells this about module dependencies:

  3.1. Kamailio Modules

  The following modules must be loaded before this module:

      tm module - (optional) if you want to have rtpengine_manage() fully functional

Looks like this is not correct.  If Kamailio connects to rtpengine over
websocket protocol, then there is dependency on lwsc module.

I haven't checked if lwsc module works without tls module when wss is
used.
