upload module 2.0.3

[Valery Kholodkov]

Changes:
  * upload_store directive was not able to receive more than one 
argument. As a result no hashed dirs for file uploads were possible.
  * upload_store_access directive did not work at all. Permissions were 
defaulted to user:rw. Thanks to Brian Moran.
  * In case of any errors at the last chunk of request body only 500 
Internal Server Error was generated intsead of 400 Bad Request and 503 
Service Unavailable.
  * Fixed copyrights for temporary file name generation code
  * Fixed compilation issue on 0.6.32. Thanks to Tomas Pollak.
  * Added directive upload_pass_form_field to specify fields to pass to 
backend. Fixes security issue found by Brian Moran.

Documentation updated accordingly:
