allow use of multipart/form-data in draft-reschke-webdav-post

Hello,

Late comment on draft-reschke-webdav-post:

Browser based applications are not allowed to upload files from the 
client filesystem by any mean other than using an HTML form containing a 
file param and an enctype of multipart/form-data. As a consequence, 
those applications have no way to upload local files to a WebDAV 
repository using PUT (my knowledge of browser based technologies is 
rather limited but I have found at least a few references to this 
limitation).

http://tools.ietf.org/html/draft-reschke-webdav-post could partially 
solve this issue by simply allowing a multipart/form-data containing a 
single subpart to be POSTed.

Modifying a resource by uploading it again would still not be possible 
of course but that can be somehow workarounded.
