veyron/examples/pipetobrowser: Adding couple of new plugins similar to *nix's /dev/null concept. 

Primary purpose of these plugins are for automated and
performance testing.

/dev/null: consumes the stream without doing anything with the data or keeping
 it in memory
/dev/null/text: consumes the stream as utf8 so it does decoding of bytes 
but does not do anything else and does not keep it in memory. 
This is useful to do performance testing on NodeJS's UTF-8 decoding code
