upr 0.2.0 - twice as good as the first!

This release fixes several bugs and adds better compatibility
with existing upload progress implementations from other web
servers.

'config.gem "upr"' in Rails config/environment should work now
that double loads are non-fatal (but still warn).  Additionally,
better error handling has been added and timeouts increased
to reduce the probability of errors due to slow clients.

The Rack backend can now generate JSON responses compatible[1]
with upload progress modules for both lighttpd and nginx.
Additionally, streaming JSON as demonstrated in
mongrel_streaming_upload_progress is supported, too.

This is a list of upload progress modules we are compatible
with:

1. mongrel_upload_progress
   http://mongrel.rubyforge.org/wiki/UploadProgress
2. jquery-upload-progress
   http://github.com/drogus/jquery-upload-progress
3. mongrel_streaming_upload_progress
