Sorted DESC on added awesomeness:

• Run maintenance/update.php after copying of code
• Archive the stuff before uploading and unarchive to upload folder on the server
• Add option to update a wiki from what's in the upload folder
• Have an option to run maintenance/runJobs.php after copying of code

Teh script
