Issue #2053 has highlighted the fact that random numbers are always generated with the same seed. An example of generating different random numbers, other than the original seed, has been added to the documentation. Furthermore srand initialization has been added to jerry-main, and targets. Update test-common.h with srand call. JerryScript-DCO-1.0-Signed-off-by: Daniel Balla dballa@inf.u-szeged.hu
