Online Update Proxy Support

[hdm at metasploit.com (H D Moore)]

Hello everyone,

Due to popular demand, proxy support has been added to msfupdate. Only 
HTTP "CONNECT" and SOCKSv4 proxies are currently supported. If you would 
like support for a different type of proxy, please contact me off-list. 
The latest version of msfupdate can be obtained via the "snapshot" 
download and of course via msfupdate :-) 

Some quick examples:

$ msfupdate -u -p http:my_http_proxy:3128
$ msfupdate -u -p socks4:my_socks_proxy:1080

If you are stuck behind an unsupported proxy, but you have access to an 
external system via SSH, you can use OpenSSH's dynamic proxy feature with 
msfupdate (and the Proxies variable in the actual Framework):

my_inside_box $ ssh -D1080 user at external.bom
my_inside_box $ msfupdate -u -p socks4:127.0.0.1:1080
