StringOutOfBoundsIndexException issue, and ParseException suggestion

[DalekCraft2]

The SNBTUtil.fromString() method throws a StringIndexOutOfBoundsException if an empty string is passed to it, so it would be convenient if that was fixed so one would not have to add catch statements for it whenever they invoke the method.

For the ParseException class, I think that it should have a method for getting the index at which the error was found. In my case, I want it so I can create a (java.text.)ParseException from it for a JFormattedTextField's formatter.

Edit: Alternatively, you could simply use the java.text.ParseException class instead of creating your own.
