* QuickHelp button has been removed in favor of a Help menu item.
* Keyboard shortcuts are now in the menus.
* Numerous fixes to subtle aspects of the wijmenu implementation.
* edit text cells on double-click instead of single-click
* render text cells on unselect instead of focusout.
Only renders when selecting another cell, and prevents rendering when
switching applications/windows/tabs.
Notebook cleanups and fixes: connection file cleanup, first heartbeat, startup flush.
Kernels would not linger, but the KernelManagers are not garbage-collected on shutdown. This means that connection files for kernels still running at notebook shutdown would not be removed.
Now, kernels are explicitly killed at server shutdown, allowing the KernelManagers to cleanup files.
Small changes along the way:
* disables the unnecessary (and actively detrimental) SIGINT handler inherited from the original copy/paste from the qt app.
* put webapp initialization in `init_webapp` out of `initialize`, to preserve convention of there being no unique code in `initialize()`.
* don't warn about http on all interfaces if running in 100% read-only mode, because no login or execution is possible.
Closes#1232.
Single-click to edit gets in the way of using interactive elements (e.g. non-flash videos),
and select/copy of the rendered HTML. Switching to double-click makes the edit action more intentional.
adds AuthenticatedFileHandler, which extends StaticFileHandler with
a simple authentication check before providing access to files local
to the notebook dir.
Heartbeats start immediately, causing false heart failures on slow systems that can take a while to start kernel subprocesses.
Also adds a 'flush' to the heartbeat callback (just like in IPython.parallel), to protect against server load being detected as heart failures.

Also disable the unnecessary (and actively unhelpful) SIGINT handler inherited from the original
copy/paste from the qt app.
Login/out button cleanups:
- Display a login button when viewing the notebook in read-only mode.
- On the login page, focus on the password field by default.
- Correctly style login / logout buttons.
- In read-only mode, redirect to "/" after logout, not "/login".
