Changes/Fixes

Flatten directory structure to support pip installing via: 
```pip install git+https://github.com/Fuzion24/AndroidViewClient.git@master```

The preceding noise discussed #deb2fdb9e95eb29fc5 happens from xposed/substrate improperly dumping stuff to stdout.  Some devices do this as well.

I have a newer version of adb that your python implementation seems to support just fine:
```
adb version 
Android Debug Bridge version 1.0.32
```

Plus, some small API additions.
