Tommi Sinivuo 3c55f067a8 Add SetRandomSeed(unsigned int seed) function (#1994) 
Specifying a fixed seed for the random number generator is often
used in games for various reasons.

By adding an api function for seeding the random number generator
we solve two different problems regarding the seeding:

1) The underlying RNG implementation does not leak to client code
   (as would be the case if we called srand directly from the
   client code)
2) Seeding the RNG would be simple from other programming languages
   (especially in cases where calling libc functions is non-trivial)
