    Use 'trimmed' for blocktrans in html page

    Add trimmed option to blocktrans, blocktrans trimmed
    option removes newlines from contents of blocktrans
    and replaces any whitespace at the beginning and end of a line into
    a single space. This makes translator life easier.
    More detail is described in the bug report.
