First stab at tiddlywebplugins.reflector, a reflector
plugin idea from Ben Gillies:

* Post a file to the reflector and it gets returned to the
  browser with the content-type it was given.
* If you put the sending form in an iframe, then you can
  gather up the content of the iframe and give it to 
  tiddlywiki for use in the import routines.
