updated to SDK 20
Merge pull request #1 from hkjellander/origin/kjellander

Origin/kjellander
Move to compileSdkVersion 20.

Instead of using explicit L preview, this allows us to run the app on
pre-L devices while still building with API 20.
Merge pull request #2 from hkjellander/pbos-api20

Move to compileSdkVersion 20.
Inflating the AppRTCGLView from XML instead of code.
Merge pull request #3 from hkjellander/origin/kjellander

Use high-resolution launcher icon.
Merge pull request #4 from hkjellander/icon_hdpi

Disconnect button (early stage).

Button that works, but doesn't look so nice yet.
Merge pull request #5 from hkjellander/origin/kjellander

Disconnect button (early stage).
Remove AppRTCGLView.

Instead, calling setSystemUiVisibility for the activity and not the
GL view. Using layouts that have been committed earlier it seems like we
don't have the need for using setMeasuredDimension either.
Merge pull request #6 from hkjellander/remove_apprtc_glview

Remove AppRTCGLView.
Some polish for the menu bar.

Centers the menu bar, puts it at the bottom and adds a debug button to
toggle the debug HUD instead of triggering on every button press.
Fix indentation.
Merge pull request #8 from hkjellander/menubar_polish
