apache 2.0 patch to force proxy to speak HTTP/1.0

This patch adds a new server config
'forceHTTP10Proxy', which when turned on will cause the HTTP proxy code to send a HTTP/1.0 request

(all it does it change the 'GET .. HTTP/1.1' to 'GET .. HTTP/1.0')

this is to allow people to use the r-proxy against broken HTTP/1.1 servers which can't be fixed (ie.. not open source)
