First dynamic version of CreativeNotes

Mobile version currently not usable while Android WRT does not allow
file attaching.

The application now it's persistent, it sends the media to a backend, as
well as the notes.  At the beggining it retrieves all the notes from the
backend.

Every note is saved in a group, this group is designed by the Webinos
PZH, so every device connected to a determined PZH will have the same
notes.

When some device has sent or updated a note, the rest of the connected
devices of the PZH will be notified.
