[API change] Change SFC format

[MayaRainer]

This is to be done as a part of a future API/protocol redesign.
Change the SFC report format to be something along the lines of SFC {action: "report", report: string, character: string, channel?: string}
channel is optional; if it is not given, the report is regarding a private conversation with character.
Have the chat server call the log creation on the site server directly instead of the extra step for the client.

Oh and let's let people set a status before logging in, in whatever the future equivalent of IDN is.
