Add support for extra meta-data in packages

The appman-packager got a few new options to add extra meta-data to a
package's header, with optional signing for important fields.

This meta-data can then be checked on installation in the System-UI by
looking at the 2 new parameters added to the
ApplicationInstaller::taskRequestingInstallationAcknowledge() signal.
