string_random
Returns a string of a given length composed of characters randomly selected from a given set. If the set is empty, the set of all printable ASCII characters will be used.
NOTE: This differs from the legacy version which could select from 256 possible characters. GameMaker's current null-terminated string handling would cause it to fail if character 0 was selected. The new default behavior using printable ASCII is probably more useful. If you need to produce random byte values, a buffer should be used.
