issue #10: add build target jdoc
move AlternateDataStream to package plugins; improve build.bat s
update run.bat; add AlternateDataStream.deleteIfExists() and tool DeleteStreams
.gitignore doc/api; NtfsStreamsJ: delete invalid MD5 stream when found, don't write MD5 stream if file has either been modified in between or is less than 32k
add script newWDX.bat for setting up a new WDX plugin project
add tool NtfsStreamsJ.DeleteStreams
improve root build.bat: don't create dist/.zip if compilation fails for a plugin; general build: don't put classes from namespace plugins into individual plugin .jar
