unit testing for gnome-games

[Andreas Røsdal <andrearo pvv ntnu no>]

gnome-games now has initial support for unit testing,
through the Check unit testing framework:  http://check.sourceforge.net/
The command 'make check' now automatically runs the units tests.

A lot of new test cases will have to be written if this is going to be 
useful. I would like that new patches and bugfixes have unit tests when 
this is practical.

Eventually, it would be pretty useful to have code coverage reports,
such as these: http://gtktests-buildbot.fisterra.org/gnomeslave/gtk+/lcov/
That would require adding support for LTP GCOV to gnome-games.

A similar buildbot could be setup on games.gnome.org, to compile 
gnome-games each day, and generate test results and code coverage.
