Defined minSdkVersion and targetSdkVersion

If not defined, manifest merger adds unneeded permissions,
giving the following reason:

  com.google.android.apps.auto.sdk.ui has a targetSdkVersion < 4

added required dependencies to pom.xml

Better proguard.txt

Added Proguard rules

Added referenced com.google.a package

Reserved ids from gearhead that may clash

Fixed "Multiple dex files define..."

fixed corrupted pngs
