[Openstreetmap-dev] OutputStream Fix

[ben at somethingmodern.com]

I've been looking into how to fix the "getOutputStream called twice" error.
After much digging over various JSP forums on how to return binary data with a
JSP (much recommend "don't"), I find these magic lines at the end of the page
do it:

    out.clear();
    out = pageContext.pushBody();
    %>

It's committed and installed.
