Changed the Android signing keys from the original actionman.keystore to start_something.keystore, since this is a different application I don't have the original keys anyway.
Updated the AndroidManifest.xml file so as to make it work for different build environments without manual editing as seemed to be the case previously.  I allowed for automated setting of build number via the addition of a Time.now_as_numbers method, which probably doesn't need it's own file and method now that I think of it, as well as automated setting of debuggable and the host or endpoint.
Rather than setting both an @assets_env variable and ENV['RAILS_ENV'] in the mobile.rake tasks, with ENV['RAILS_ENV'] being used in the altered AndroidManifest.xml.erb file, I just swapped out references to @assets_env to ENV['RAILS_ENV'], and did a little tidying as well.
