NEW: Added replaceExistingFile setting for UploadField.

Browse Source 
Sometimes has-one UploadFields can get confused about whether or not there is an existing file that needs deleting.  This setting lets you make a more robust has-one UploadField, where any existing file will be replaced.  It more closely mimics simple single-file upload fields.
