Added <options/> support to Proguard configuration

Additional Proguard options can be added using an <options/> element,
allowing to configure the plugin in a super POM.
fix: use parsedOptions instead of proguardOptions
Create a copy of manifest file and use it further.

Old mojo updated the original manifest, which could create issues if
the plugin is bound to the build process, especially during releases.

The new approach allows to create a copy of the manifest (usually
${project.build.directory}/AndroidManifest.xml) and use it to create
the APK.

This creates the possibility to use buildnumber-maven-plugin or other
extension if desired.
