notebook option to upload a .sws file

[sagetrac-olazo]

It would be great for those of us who have installed Sage to be able
to double click on these files and have sage open them in the
notebook.

Suporting a command on the likes of:

sage -notebook /path/to/worksheet.sws

would be a very good step in this direction.

No patches need to be applied. There is an upstream pull request on github, merged in #13121.

Syntax is

sage -notebook upload="/path/to/worksheet.sws"

The changes to extcode (specifically for the Mac app) have been moved to #11026.

Depends on #13121

Upstream: Fixed upstream, but not in a stable release.

Ticket #693 is related.

What would be needed for this? #693 shows that it's possible to know whether the notebook is running and then open the browser or not based on this. And http://foo.sagenb.org/home/me/upload_worksheet shows that there is a script to take a .sws file and send it straight to the browser. So I say this is definitely doable by someone who knows these scripts. Is this right?

This also led to the following - #9875.

Depends on #693

I have added support for uploading from a file:// url in order to support sage --notebook upload=FILE.sws. The sagenb patch allows this, and the extcode patch adds support to the Mac application. I had to support file urls so that the upload url could be given as a GET rather than a POST request, and hence be passed to any browser.

The Mac app has a new option to automatically start the server when a sws file is opened. I'm not sure anyone would ever want to turn this off, so I can remove it if it's not useful.

I should note I only allow file urls when running on localhost because otherwise it doesn't make much sense and could be a security hole.
