**BUG**
Concise problem statement:
Steps to reproduce bug:
1. Open EasyEDA in chrome.
2. Open EasyEDA in FireFox
3. Edit.
Results: PCB schematics and boards are not updated with changes made elsewhere. Often projects and parts are completely empty. Currently, I cannot get a board to refresh to a state where I sent it off to fabrication.
Expected results: Boards should be the same if refreshed and edited.
Browser: Chrome, Firefox.
