Write places of encryption salt into documentation (wiki)

 I would suggest to write into the documentation (in this case the wiki) where the enryption salt strings are located.

Because I took the string "Ch4ng3^M3" literally and changed it to a secure string of mine. But i changed only in server and validation script and wondered then why it does not work. Messed up by reverse engineering (writing console.logs into the server.js and so on...) until I found the salt again in client/js/lib/socketbug_console.js...

Just a suggestion if there exists more encryption_salt_changer except me ;-)
