Uninitialized value in _priority

Valgrind reports:

This is the offending line: https://github.com/trolando/oink/blob/257d0d088361204449c9bb204b457c2042e26cae/src/game.cpp#L276

This is because _priority is not calloced but malloced here: https://github.com/trolando/oink/blob/257d0d088361204449c9bb204b457c2042e26cae/src/game.cpp#L127

This should read:

_priority = (int*)calloc(v_allocated, sizeof(int));

(Or better yet, as this is C++:

_priority = new int[v_allocated] {};

)
