Update Version Number in AndroidManifest with POM version number.

update-manifest.xml

<!--
 Include the following snippet in a profile or as part of your standard build.
 It will parse out the POM version number and then use it to update the
 version number in your AndroidManfiest.xml.   It will also increment the
 versionCode based on the version number.
 
 No more manually having to update the vesion number as part of a release!! Yipee!
