Which versions of NPA should be used for the app?

[Ethrel]

As of right now, the only version of npa that is available to be injected is the alpha version. If there is demand, I'm sure myself and anicolao could set up the ability to use either.

To accomplish this, off the top of my head, these are the basic requirements:

• anicolao would need to set up a stable branch host somewhere (or I'd need to pull, build, and host/include stable tags somehow).
• I would need some kind of a ui somewhere to allow setting which version would be used.
