Thanks to a report by Stefan Cornelius, we became aware that the flame
plug-in does no checking for correct input when loading a pre-saved
settings file.
I reworked the parser to read one or more values based on the type of
token, making sure we also don't read past the end of our token buffer.
All int values have a min and max value set. If any unexpected input is
encountered, we will give a warning.
