Add Entries.push() method, push a state to the server
Cleaner Entries.contentEditAutosize()
Fix Entries.push() condition
Add pull, improve push
Some refactoring
Entries.pull() is working, can share the board accross computers BUT huge CPU usage with pull.php : needs to be recoded
Add Boardo.Client class. Some refactoring still needed. Push/pull.php are working, buggy in js.
