[sr-dev] extra_hdrs param to imc module

[Juha Heinanen]

it looks to me that

LM_ERR("command: [%.*s]\n", cmd->name.len, cmd->name.s);

should be changed to 

LM_DBG("command: [%.*s]\n", cmd->name.len, cmd->name.s);

since it is printed every time when imc_parse_cmd is called
successfully.

this does not still explain, why imc server does not send 200 ok
response to the #join message.
