[e4-dev] Copyrights

[John Arthorne <John_Arthorne@xxxxxxxxxx>]

I noticed recently that quite a lot
of e4 source code was missing copyright headers. I fixed the cases I saw,
but just wanted to remind people to setup their Java code templates accordingly
so that copyright headers are inserted when you create new files (the "New
Java files" code template). The platform releng tools also have a
utility for double-checking that copyright statements are present and up
to date.
