missing function call in class.obfuscator.php

[Demodian]

Line 32 of class.obfuscator.php currently reads:

$substrFuncName = "_" . self::randomString(4, 9);

and should read

$substrFuncName = "_" . self::randomString(rand(4, 9));

because self::randomString expects only one length argument and every other use of it has rand() for the range.

The current implementation will always make a string of length 4.
