NetNewsWire 7.1.1 for iOS

Changes since 7.1:

• Handled Reddit’s new rate limiting (one feed per minute) by refreshing just one Reddit feed — the least-recently-checked one — per refresh session
• Stopped scaling up small feed images — the blurriness is worse than the smallness
• Fixed bug where transparent pixels in a feed icon were counted as black when picking a background color
• Fixed text contrast bug when swiping an article in the timeline
