Updated patch per kkolinko's review:

1. Fixed backward-compatibility
   - Tomcat 6 release will now function properly in its default configuration
     with an older tcnative (protocol "all" remains == "TLSv1" instead of
     including additional protocols). I considered making it auto-switch
     but that would likely be confusing to users.
   - Updated "recommended" tcnative patch level to 1.1.32 in
     AprLifecycleListener.
2. Updated documentation
   - Fixed XML structure of changelog
   - Less invasive change to APR configuration (http.xml -> apr.xml)
   - Fixed protocol count
