This will add functionality to add installLocation & uses-feature entries into AndroidManifest.xml, to allow for installing on SD card and to make hardware features like camera to be optional, to allow apps to show up on the market for more devices if there's a non-essential optional hardware use case.
Attached is a diff (without documentation changes) relative to 2012-10-24 snapshot.
Build.xml syntax like this:
<variable name="polish.build.android.features" value="hardware.camera/false,hardware.microphone/false,hardware.touchscreen"/>
/false will set required flag to false, default is true, like in http://developer.android.com/guide/topics/manifest/uses-feature-element.html
<variable name="android.installLocation" value="auto" />
