Initiated migration to CouchDB.
Removed unused files.
Reimplemented all the logic using a JSON file as data source.
Added 'couchdb-conduit' dependency (deps/ dir) and made it work with my current dependencies (see deps/ for the list of versions).
Deleted unused dir.
Persisted data in CouchDB instead of a file.
Started implementing changes in the protocol regarding messages' formats and messages' recipients. 'auth-server's code is broke.
Forgot to add some files.
Fixed 'auth-server's code and almost finished implementing the protocol (server-side). Needs some more testing and integrating criptography.
Updated .gitignore.
Merge branch 'couchdb'
