support for id-based translations

unlike in an earlier attempt, ids are textual this time.

the developer is able to provide a template for the string. when lupdate
and lrelease are integrated into the build process, this makes it
possible to avoid a round-trip to a dedicated string designer during the
early development stage.

Requirement-id: QT-435
