Changing Android package to have no max API version for target

@bhariharan says there's no real point in limiting the upper bound of a developer's target API.  Also, changed the min target api to 17.
If ```unstable``` is not specified here, it automatically makes ```minApi=8```, since it pulls from ```master```. This leaves this broken on ```unstable```. We'll need to remember to remove this when we release though.
