Merge lp://qastaging/~cszikszoy/docky/proxydocky into lp://qastaging/docky

Ignore lines 55-58 of the diff. That was just there for debug. I've already removed that in my branch. It's now just:
return GConf.Get<bool> ("/system/http_proxy/use_http_proxy", false);

Looks good!

My only comment is I wonder if we can cache the proxy settings and then only update them if gconf changes? As it is now, every web request will incur like 3 calls to gconf (assuming there is a proxy), which means if you have weather setup for every 15 mins, gmail for every 2 mins with 4 labels, npr, etc... you will have a *lot* of calls to gconf which probably arent needed!

I seem to recall the example in the bug report cached. ;-)

It would be really nice if we could do this. We don't have any sort of way to monitor GConf for changes as of right now. Any ideas how we could do that cleanly?

I put code into GNOME Do that did that, take a look there how it is done. Basically you can tell gconf to notify you when a certain path changes.
