* Added autoload section to xml config file and got rid of the -p option (preload).
* To load your old config file, rename it to blah.tcl and put <script>blah.tcl</script> in the autoload section.
* Added sample config.xml and config.tcl files.
* Moved some more script functions to the script module.
