- Added additional check to see if apk has internet permission for selendroid
- Updated appium-adb 
- Added seledroid test
- #3146
I would wrap within 80 chars like this:

```js
var errorMessg = "apk does not have INTERNET permissions. Selendroid needs internet " +
                            "permission to proceed, please check if you have <uses-permission " +
                            "android:name=\"android.**permission.INTERNET\"/> in your " +
                            "AndroidManifest.xml";
```
(or wherever the breaks should actually be)
