Cleanup JDT vs. ECJ:

Cleanup JDT vs. ECJ:

- Replace "jasper-jdt.jar component" with "Eclipse JDT Java compiler"
  in license texts

- Add JDT version to our ant version filter
  and replace explicit version in release notes file with version tag

- Replace "jasper-jdt.jar" by "ecj-*.jar" in generated documentation.
  I assume people know what we mean by "ecj-*.jar".
  We shouldn't maintain detailed versions in those pages. Alternatively
  running them through the filter means either adding maintenance by
  keeping the file list up-to-date or much overhead by running all of
  them through the filter.
  Renaming the ecj-*.jar to simply ecj.jar or ecj-3.jar would hide
  the full version from the interested observer.
