Updated project to work in Android Studios (Gradle)

Updated project structure and project files; updated library namespace
to just 'amvvm' now. Made some slight tweaks to IViewModel. It appears
to at least run with no issues on Nexus S. Layouts will still show
'error' in Android studios, but doesn't keep it from building.
