add FileFindHandler for Notebook static files

[minrk]

The static file handler now uses a search path, instead of a single dir.

This allows easier customization of available js/css,
and provides a place for extra files to go for extending the notebook.

An empty custom.js / custom.css are added to the templates for trivial custom user styling/scripting.

The search only happens once, and the result is cached after the first.

hum, this is completely broken for me.
I need to override

+    @classmethod
+    def make_static_url(cls, settings, path):

otherwise it say that path is a list and have no attributes endwidth('/')
it still complain that cls._lock does not exist.

also get is not decorated by @authendicated...

I guess there is a commit missing ?

[minrk]

It works for me, so maybe it is a tornado version thing. I will look into doing this more carefully, and checking against various tornado versions.

also get is not decorated by @authenticated...

get must not be authenticated, or you would not even be able to see the login page without having logged in already. The default StaticFileHandler does not authenticate.

here is the traceback of tornado.

and I pushed a crude thing of copy/past/things I did to make it works in Carreau/_Staticfiles

also

In [3]: tornado.version
Out[3]: '2.1.1'

[Carreau]

StaticFileHandler._lock only exist since 2.2.0.
make_static_url also have some recent changes.

[minrk]

Thanks, I will look more carefully at the diff between our baseline dependency (2.1.0) and 2.2-dev, and push again in the next day or two.

[minrk]

tested against 2.1.0, and fixed by pulling a few more methods from current tornado verbatim.

[Carreau]

Great ! I'll test that ! It'll be cool to load js extension !

[Carreau]

That's perfect, don't even need to provide user-custom templates as you can just inject any other change or file you want into the page with custom.js and jQuery.

The only issues I see is that you might hate to install things on every profiles. Does windows allows stuff like symlinks ?

[Carreau]

ha ! I didn't saw the extra_static_path configurable.
That's perfect then !
Merging in 24h if no objections.

[Carreau]

i'll merge this guy which is great.
