This commit provides following editor config:
- Tabs, not spaces
- Unix (LF), not dos (CRLF) line endings
- Eliminate all trailing whitespace
- Latin-1 (ISO-8859-1) encoding for Java sources; use native2ascii to convert if necessary
Following convention cannot be set by editorconfig (only vim and emacs support maxline length of editorconfig):
- Aim to wrap code at 120 characters, but favor readability over wrapping
