* Create a new remote server that will listen for order on the given port.

* The available commands are given as arrays of objects (first item is the key,

*
* The md5 is always a String (the MD5 hash of the access key), the commands are
* also Strings; the parameters vary depending upon the command.
*
*
[md5] PING: will return PONG if the key is accepted
*
[md5] GET_METADATA *: will return the metadata of all the stories in the
* library
*
[md5] GET_STORY [luid]: will return the given story if it exists (or NULL
* if not)
*
[md5] SAVE_STORY [luid]: save the story (that must be sent just after the
* command) with the given LUID
*
[md5] DELETE_STORY [luid]: delete the story of LUID luid
*
[md5] GET_COVER [luid]: return the cover of the story
*
[md5] GET_SOURCE_COVER [source]: return the cover for this source
*
[md5] SET_SOURCE_COVER [source], [luid]: set the default cover for the
* given source to the cover of the story denoted by luid
*
[md5] EXIT: stop the server
