Added SOCKS5 proxy support in preferences

[jim618]

Add SOCKS5 proxy support, as suggested by Haley Amlin, Gary Rowe as follows:

http://stackoverflow.com/a/120818/396747):

if (needsProxy()) {
System.getProperties().put("proxySet", "true");
System.getProperties().put("proxyHost", getProxyHost());
System.getProperties().put("proxyPort", getProxyPort());
} else {
System.getProperties().put("proxySet", "false");
System.getProperties().put("proxyHost", "");
System.getProperties().put("proxyPort", "");
}

java -jar -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=8123
multibit-exe.jar

will this protect for any possible leak?

[jim618]

It needs more investigation with something like WireShark before I can be sure there is no leaking of data.

Currently the help is sited at http://multibit.org so that is a leak. DNS lookup is used to find the peers so that might leak too.

I also vote for SOCKS support. It is the a basic function for the software. I can imagine all kinds of anonymous transactions, but your IP is stamped in the transactions leading to immediate and certain identification of each movement. This alone makes the client a big hazard to use.

+1 This should be a built-in feature.

+1 for building this feature into the wallet's GUI, or configuration file at a minimum.
