Change '+' to spaces in file name during file download #237

If filenames have spaces during download the spaces are changed to "+". So if file name is "my picture.jpg" Firefox loads a file as "my+picture.jpg". I've seen this issue only in Firefox, but possibly it occured also in another browsers.
I've found 2 places for file download in Omnifaces. The solution can be replacement of "+" to "%20". Tested with Ie8, Ie11, Firefox, Chrome


        externalContext.setResponseHeader("Content-Disposition", String.format(SENDFILE_HEADER,
            (attachment ? "attachment" : "inline"), encodeURL(filename)));


        externalContext.setResponseHeader("Content-Disposition", String.format(SENDFILE_HEADER,
            (attachment ? "attachment" : "inline"), encodeURL(filename).replace("+", "%20")));


String filename = encodeURL(getAttachmentName(request, resource.file));

#237: clarify encodeURI javadoc and fix FileServlet filename as well
(it's unnecessary on ETag and for backwards compatibility I'd rather not
change it)
