Fixed issues with client-server communication.
implemented the ui to be able to have multiple shared notes windows opened and being shown for every user in the session
Merged multinotes-ui (client ui) and multinotes (server logic)
Using server to provide sharednotes numbering.
fixed the inconsistency when a particular note is closed and it's not possible to close the others; cleanup
enable open and close additional notes only for moderators; using an attribute on config.xml to enable or disable multiple notes support
localizing the modifications on the shared notes for en_US and pt_BR
