Please backport hedgewars 0.9.21-3 (universe) from vivid

[Gianfranco Costamagna]

Please backport hedgewars 0.9.21-3 (universe) from vivid to utopic, trusty, precise.

Reason for the backport:
========================

New features, as usual hedgewars needs a backport

Testing:
========
Mark off items in the checklist [X] as you test them, but please leave the checklist so that backporters can quickly evaluate the state of testing.

Builds available at ppa:costamagnagianfranco/locutusofborg-ppa
* utopic, trusty, precise:
[X] Package builds without modification
[X] hedgewars-data installs cleanly and runs
[X] hedgewars installs cleanly and runs

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

[Gianfranco Costamagna (costamagnagianfranco)]

I can't test utopic, since virtualbox is having troubles in setting up the VM

[Gianfranco Costamagna (costamagnagianfranco)]

precise is working perfectly

[Gianfranco Costamagna (costamagnagianfranco)]

trusty is also working, my personal machine
