Fix commit: PUT request now correctly handled by Pharo Zinc

[lolgzs]

Commit looks big because order has changed (??)

The only diff is:

ajax: anURL options: #{ 'type' -> 'PUT'.
'data' -> aString.

•            'contentType' -> 'text/plain'.
           'error' -> [window alert: 'PUT request failed at:  ', anURL] }
