Title: Fix ability to leave addons packed

It looks like `_addExtension`'s `unpack` argument was never used -- this fixes that, reading the info whether or not the addon can be packed.

I added `fs-extra` to copy files synchronously, but if you'd rather less dependencies, I can make a utility function to do the copying of the xpi for packed addons if you'd like -- let me know!
