New embryo function: get_program_id

It is now you can run programs with names generated dinamically. Say that you
have 10 programs indexed somehow. You can now call them using the following snippet:

script {
   new program_id[15], i;
   for (i = 0; i < 10; i++) {
      snprintf(program_id, 15, "my_program_%d", i+1);
      run_program(get_program_id(program_id));
   }
}
