HEAD
- fixes for randnumber generation
- due to a error in coding the 64bit and 64bit2 rnd seeds were throwing away the second half of the seed, we now preserve this functionality and make it explicit
- additionally 64bit3 now uses all 64bits of the seed
- also added new function pushrandomnumber poprandomnumber to be called instead of setrandomnumber before we were crunching the Safe space random number generator state, as this function is used bu thing the <optionresponse> and <radoibuttonresponse> this meant changes in the internal randomization code could screw up later Safe space random calls the old method is preserved for blank 64bit and 64bit2 randomiztion env.
