Add proxy support about csharptest-net HOT 2 CLOSED

I still don't get why .Net doesn't do this by default. annoying.  Next time I 
release JiraSvn I'll get this change merged and verified.

The GitHub project has been updated to support authenticated proxy servers.
https://github.com/csharptest/JiraSVN

Though I have not yet included this commit in the installers, if you have a 
chance I'd appreciate you getting/building/testing this fix if you have a 
chance.  The fix is in two parts:

1. Setting UseDefaultCredentials = true; on the jira web service.  I suspect 
this will be enough to enable you to work properly.

2. Added an App.Config setting "jira:proxyurl" which can be supplied with a URI 
to a proxy server.

I suspect this will just work for you; however, if you're unable to connect 
after a clean install try setting the proxy server manually in the 
SvnPlugin.dll.config file.

Let me know if this solves your issues.

Thx
