@gvaish toggle-all must be checked if all are checked and vice-versa

* .gitignore: Ignore swp and ~ files.
* base.css: Why rotate?
* binders/index.js: _resyncUI - ensure that toggleAll is checked if all items are completed
* controller.common-tests: Mock addBlob
* DONOTDELETE: deleted
* todo.common-tests.js: init and getAll tests
