NodeJS eLock server

Distributed locking server on NodeJS.

Implements Dustin's eLock server protocol with following additions:

• deadlock detection: lock command may return 423 error code with a detailed deadlock description.
• value lock: lock_value key value [timeout] locks the key to be equal to value. Many client sessions can lock the key to the same value at the same time. Return codes are same as for the lock command.
• debug command. Expected output:

  200 DEBUG
  SESSION <session 1 object JSON>
  SESSION <session 2 object JSON>
  ...
  LOCK <lock 1 description (free text)>
  LOCK <lock 2 description (free text)>
  ...
  REQUEST <lock request 1 description (free text)>
  REQUEST <lock request 2 description (free text)>
  ...
  END
