Remove HTML5 parser java docs and generation code.

java->C++ automated translation is not something we want to deal with
now or in the future.

-If this is your first time building the HTML5 parser, you need to execute the
-following commands (from this directory) to bootstrap the translation:
-
-  make sync             # fetch remote source files and licenses
-  make translate        # perform the Java-to-C++ translation from the remote 
-                        # sources
-  make named_characters # Generate tables for named character tokenization
-
-If you make changes to the translator or the javaparser, you can rebuild by
-retyping 'make' in this directory.  If you make changes to the HTML5 Java
-implementation, you can retranslate the Java sources from the htmlparser 
-repository by retyping 'make translate' in this directory.
-
-The makefile supports the following targets:
-
-sync_htmlparser:
-  Retrieves the HTML parser and Java to C++ translator sources from Mozilla's 
-  htmlparser repository.
-sync_javaparser:
-  Retrieves the javaparser sources from GitHub.
-sync:
-  Runs both sync_javaparser and sync_htmlparser.
-javaparser:
-  Builds the javaparser library retrieved earlier by sync_javaparser. 
-translator:
-  Runs the javaparser target and then builds the Java to C++ translator from 
-  sources retrieved earlier by sync_htmlparser.
-libs:
-  The default target. Alias for translator
-translate:
-  Runs the translator target and then translates the HTML parser sources 
-  retrieved by sync_htmlparser copying the Java sources to ../javasrc.
-translate_from_snapshot: 
-  Runs the translator target and then translates the HTML parser sources 
-  stored in ../javasrc.
-named_characters:
-  Generates data tables for named character tokenization.
-clean_javaparser:
-  Removes the build products of the javaparser target.
-clean_htmlparser:
-  Removes the build products of the translator target.
-clean:
-  Runs both clean_javaparser and clean_htmlparser.
