Please backport supertuxkart 0.8.1-2 (universe) from trusty

[Oibaf]

Please backport supertuxkart 0.8.1-2 (universe) from trusty to saucy.

Reason for the backport:
========================
New upstream release with new features.

Testing:
========
Succesfully backported in my PPA here: https://launchpad.net/~oibaf/+archive/graphics-drivers/+packages

* saucy:
[X] Package builds without modification
[X] supertuxkart-dbg installs cleanly and runs
[X] supertuxkart-data installs cleanly and runs
[X] supertuxkart installs cleanly and runs

Reverse dependencies:
=====================
The following reverse-dependencies need to be tested against the new version of supertuxkart. For reverse-build-dependencies (-Indep), please test that the package still builds against the new supertuxkart. For reverse-dependencies, please test that the version of the package currently in the release still works with the new supertuxkart installed. Reverse- Recommends, Suggests, and Enhances don't need to be tested, and are listed for completeness-sake.
