Added NNTP proxy server option for tmux scripts

The proxy server provides connection pooling and handles compressed headers in a manner transparent to the current scripts. This removes the latency caused by creating and destroying connections esp. if using SSL. The proxy uses compressed headers/data by default and decompresses the headers/data in a streaming fashion, passing the decompressed data on. This technique is a huge improvement over the current method which attempts (poorly) to find the end of the compressed data (buffering the entire content in memory) prior to decompressing it.

Hope you find this helpful.
