Frost message URI

Frost messages are uploaded to the message queue that must be predictable in nature. There exist two kinds of boards: signed and unsigned. Signed boards have their messages uploaded to Signed Subspace Key (Freenet), while unsigned upload to Keyword Signed Key (Freenet).

The URI is formed in the following way:
 * Signed
 * TODO - FILL ME IN
 * Unsigned
 * "KSK@"
 * "frost"
 * "message"
 * namespace (almost always "news")
 * date in the format YYYY.M.D (single digit days and months are used as single digits)
 * the name of the board
 * sequential number of the message
 * ".xml"
 * the name of the board
 * sequential number of the message
 * ".xml"
 * sequential number of the message
 * ".xml"

Example: KSK@frost|message|news|2009.2.18-frost-0.xml�
