Recognize YouTube attribution links
Remove YouTube link overriding in WebView

An unrecognized YouTube links that redirects to another YouTube links
can lead to an annoying popup so remove the overidding. I don't think
this case happens very often anyways.
Rename sort menu item to be more specific
Add some missing Override annotations
Show karma counts in account list activity

Also remove the duplicated code of AccountNameAdapter by adpting
AccountResultAdapter to use different layouts.
