Updates:
- use config object to find and load config file
- use single database object with config passed in constructor
- use settings object with database passed in constructor
- parse command line options with for loop so order no longer matters
- store all passed options in the super global $_REQUEST array for easy reference and debugging
- add debug and debug_level options for command line
- allow dumping the command line arguments when debug_level is 3 or higher
- add config option in command line to set location of config file
- add a shutdown function to allow for the exit command to be used but still output to either console or file
- add extra checks for options that are needed during runtime
- remove old PHP version 4 code
- add is_file check when checking for a valid .tiff file because file_exists returns true if it's a directory or file
