Multi-Process test build 2

This is an experimental build intended for testing.

Includes

• changes to allow running with a multi-process app setup per #479
• never stop scanning on devices that detect multiple beacon advertisements per scan per #491

To use this release, you must download the aar file below, and configure it with your project like so:

• Create a /libs directory inside your project and copy the android-beacon-library-2.9.2-mpb2.aar file there.
• Configure your app's outermost build.gradle File to reference the /libs directory from above in a flatDir declaration:

      allprojects {
          repositories {
              jcenter()
              flatDir {
                  dirs 'libs'
              }
          }
      }

• Add the library AAR as a dependency, along with the Android Beacon Library like so:

      dependencies {
        compile 'android-beacon-library-2.9.2-mpb2@aar'
      }
