move settings to the tornado settings dict,
rather than a mixture of tornado settings and application references,
and application.ipython_app references.
removes any reference to application / ipython_app attributes in the handlers,
in favor of the tornado settings dict.
These were a massive pain for anyone who might want to re-use our handlers.
Simple less classes
Simplify class handeling in js/css
Instead of setting several class (e.g: `cell vbox`) per dom element, use less to embed the definition of `vbox` into `cell`.
This should allow :
- more easy theming.
- responsive css on nbviewer
There are many other places where this can be done.
CM configurable Take 2
Change the way configurability works.
Config dict should be passed down to the parent class where it will be
merged with the default value and propagate to this only in the base
class.
This allow to both alter the configuration on a per instance basis, or
globaly by tempering with the class instance.
This also get rid of IPython global in some cases.

Still not **perfect** but I think this is the limit of my js knowledge, there is a minimal amount of code of 4 line to propagate the configuration :
```
var options = {foo:bar}; // default options can be class parameter
var overwrite_options ={boo:baz}; // came from args, or not
options = this.mergeopt(CodeCell, options, overwrite options);
IPython.Cell.apply(this,[options]);
```
generally not necessary, but sometimes the kernel connection can be dirty.
We have only seen this by starting a qtconsole via %qtconsole,
then killing the kernel, at which point the original notebook's connection
(at the zmq level) is never restored to the new kernel at the same endpoint.
It's weird, and probably a zmq bug, but a simple reconnect seems to solve it.
- MultiKernelManager no longer has IOLoop affiliations
- move connect_[channel] method to base KernelManager
- connect_[channel] wraps in ZMQStream in IOLoopKM subclass
- add KernelRestarter base class
- use decorators to minimize code in wrapped KM methods

The easiest way to see how slow the old way was is to create a very large traceback (e.g. max recursion), which bring everything to a screeching halt (even future page loads, if the output is saved). Now a max recursion error draws in a second or two.
closes#3198
fix notebook completer redraw on metakey press
- set <select> tag to style="width: auto" to fit complete autocomplete string in drop down menu
- handle special keys better, so shift, ctrl, pgup, pgdown et al work as expected in the drop down list (i.e. pgup/pgdown/home/end move selection, shift, ctrl, caps lock do not restart the drop down menu)
