HTTP proxy: accept the 'Proxy-Connection' header.

Browse Source 
FreeProxy sends this as a substitute for the standard 'Connection'
header (with the same contents, i.e. 'keep-alive' or 'close' depending
on whether the TCP connection is going to continue afterwards). The
Internet reckons it's not standard, but it's easy to recognise as an
ad-hoc synonym for 'Connection'.
