* Adjust I2PTunnelHTTPServer so it can be used for outproxy operators
(just specify the spoofed host as an empty string), allowing them to
honor x-i2p-gzip encoding.
* Let windows users build the exes too (thanks bar and redzara!)
* Allow I2PTunnel httpserver operators to disable gzip compression on
individual tunnels with the i2ptunnel.gzip=false client option
(good idea susi!)
