error in recommended plugin example

[Chris Stephens <ch...@liveoakinteractive.com>]

The reccomended plugin example has a compile error due to a missing 
library the error is:

compile:
     [echo] Compiling plugin: recommended

/usr/local/nutch/build/recommended/classes

This can be fixed by adding import org.w3c.dom.*; to the imports section 
of RecommendedParser.  Can someone update the wiki page?  I know this is 
minor, but it can be a pain for neophyte Java developers like myself.
