/**
* PUT method handler
*
* Reimplemented to safely rejected PUT with Transfer-Encoding: Chunk, if server does not support it.
* Currently on Apache with mod_php and newer Ngix support it.
* We reject it with "501 Unimplemented" for fastCGI, if SERVER_SOFTWARE does NOT contain Nginx.
* This stops OS X Finder from destroying files.
*
* @param array parameter passing array
* @return bool true on success
