Large change.
Got the items working again, bit different implementation than Steven proposed.

itemsdb still needs work, at the moment not working.
Got the dbase working now for items
@steveno: The items concept took some damage in it because underscores are not allowed in pouchdb
Think I got the db and items right now.
The items are honouring their object status better with getters/setters now and the data is private again with underscores.
Cleaned up localdb references
Fixed an issue in mapwidget (item.status() instead of item.status)
Forgot some 'flatten' commands for sending the items in ws
Some new simple widgets
