Mention hazard level number during planet generation

[Thrake]

As fun and flavourful the hazard levels are, it's not straightforward to guess how to rank nightmarish death, terminal death and unfavomable death. At the same time the hazard exposure level has a strong impact on the game, so knowledge of the exact level is important.

Therefore it would be welcome that the game mentions the numerical level of the hazard during planet generation, ie. terminal death (10) instead of terminal death.
