partial fix for disabling pausing when linked #83

Check if link mode is active in GameArea::Pause() and refuse to pause if
it is.

Remove the check for the app not having focus with pauseWhenInactive
enabled in GameArea::OnIdle() as this is now handled in
MainFrame::OnActivate() (which receives focus events) since f10e2e99.

Revert 13f5afa9 which tried to check for link status in
MainFrame::MenuPopped() because it was completely wrong and the link
check is better done in GameArea::Pause().
