Please review and upload sdl-stretch 0.3.1-2

[Manuel A. Fernandez Montecelo]

Hello,

Here it is, not very important changes, but still some updates to
better prepare it for wheezy:
http://anonscm.debian.org/gitweb/?p=pkg-sdl/packages/sdl-stretch.git;a=summary

I need Dominique to sponsor the upload.

BTW, the package looks stagnant/dead upstream (no updates since ~3
years ago) and there are no other packages depending on it (at least
in main), and quite low popcon (~100).  Maybe we can consider having
an RC bug on it so it doesn't actually enter into next stable release.
 What do you think?

Cheers.
