init: --android-home for forcing the path to the Android SDK

This allows the user to set the path to their Android SDK from the command
line. This option is named after the standard env var ANDROID_HOME, as used
in the build.xml generated by `android update project`.  --android-home
takes precendence over the ANDROID_HOME env var if it is set.
