Julian added this in a recent commit, but has told me that he does not
think it is necessary, and that I am free to remove it if it is

removed as the workspace does not specify an explicit encoding."
* Fix pom.xml to be like other projects
* Check for existence of nodejs download before re-downloading
* Fix Eclipse config files to be like other projects

folder in corresponding output entry 'output..'" warnings in the
"Plug-in Development" category.
Specifically, these are all warnings of the form "The
'javacProjectSettings' build entry should be set when there are project
specific compiler settings".
