Normalize line endings

It seems that JSatTrak was initially developped under Windows and code was stored with CRLF convention. Such convention induce difficulties when hacking on an Unix system.

Best practices require that files are stored in Git following LF convention and converted to the host system's convention in working directory.

This change can produce a lot of conflicts when merging with branches not following the same line ending convention. In this case, you should use 'git merge -Xignore-space-change ...'.
