add hashlib.crc32
public ObjectScript::getTimeSec
OS 2.5-rc is big update:
+ improve compare of complex types, for example
  function vec2.__cmp(b){
	var x, y = @x <=> b.x, @y <=> b.y
	x < 0 && y < 0 && return -1
	x > 0 && y > 0 && return 1
	x == 0 && y == 0 && return 0
	// else is not comparable
  }
+ add maxx call stack detection
+ improve error handling
+ add hashlib.crc32
* add ObjectScript::getTimeSec
* add OS::getRand and so on functions
* improve callF by performance
