Auto-build extension

[fwenzel]

In pdf.js's readme file, there's a link to a xpi built off of trunk. I think we should do the same (probably on the dev server)?

@tofumatt do you run an update script on there?

[tofumatt]

@fwenzel I don't currently, but it's part of what I'm working on. We don't really have sexy node.js setups (yet).

Do we just need the SDK + headless Firefox to build the extension? That wouldn't be hard to script, if I recall the last time I built an add-on.

[fwenzel]

I don't even think you need Firefox to build it(?) Doesn't cfx build just run a bit of Python to bundle up the code? To run tests, yes you'd probably need Firefox.

[tofumatt]

Oh sweet. I've never tried without Firefox so I didn't want to assume. That's awesome then. Thanks.

If you don't want to build it yourself (cfx xpi from the addon/ directory), you can grab a recent version at http://people.mozilla.com/~elee/newtab.xpi

I'd love to build it myself; then we can have the most recent version always available. It's an easy-to-automate thing.
