Add support for a :nowrap tag at the beginning of descriptions.

Instruct the game that the entry doesn't need to be unwrapped, and the
(upcoming) new transifex interface to not wrap it.
For some entries, like in tutorial, wrapping actually impair readability and
can make it hard or impossible to achieve proper formatting.

More tags could be added to give meta information on entries which could help
translations. I'm thinking of stuff like :gender or :plural. They could take a
value too. They'd need to be parsed earlier though (db loading?) and stored
somewhere.
