Buf Gixes (something different for a change)

Fixed the following bugs:

1.) If the install script encountered certain errors, only the message
"Installation Failed!" was displayed.
2.) Some entries in the debug array were being overwritten by later
entries that had the same generated index.
3.) In the function parse_condition_tag(), mixed content AIML wasn't
being parsed.
