Title: intensity measure type for UHS is always SA

This branch fixes "UHS calculator set correct IMT", https://bugs.launchpad.net/openquake/+bug/984734

For UHS calculations we don't really require the intensity measure type (IMT).
However the OpenSHA lite code breaks if don't provide the IMT.

Per D. Monelli the best compromise is to hard-code the IMT for UHS calculations
to SA (spectral analysis) and this is the approach taken here.

Please let me know what you think.
