readded ArrayQuery as a submodule
added *.swo to .gitignore
fixed permissions issue for file uploads

php whoami is _www so I did:

sudo chown _www ~/Sites/Lux/FileUpload/uploads/ # the upload target dir
sudo chmod 0755 ~/Sites/Lux/FileUpload/uploads/

note that
    (1) the tmp_upload dir is still the sytem default: /var/tmp/
    (2) /var/tmp permissions are set to 1777 and the dir is owned by
        alexcannon

also added output msgs to upload.php
adds uploaded file to dir accding to filetype
deleted uploaded pics
