If `mvn install -Dandroid.renameInstrumentationTargetPackage=xxx` just builds selendroid with a particular bit in the manifest which is easy to swap out later, then we don't have to, I guess. I didn't know whether all it did was determine strings in a manifest.

If that's the case, I'll change the logic to have reset.sh build the server binary and then simply change its manifest when we need to automate a given app.

As you probably saw, this only happens once, even if you run multiple tests, so it's pretty snappy.
