v0.11.0 — more reliable when the network or GPS misbehaves

• Retries a failed request instead of giving up on a one-off network blip, and stops hammering a dead endpoint when the failure isn't transient (#22)
• No longer reports a parsing bug as "offline" — connectivity and app errors are now shown separately (#22)
• "Locate me" always moves to your current position instead of sometimes doing nothing if you hadn't moved far (#22)
• The bus-position fade now starts at the same point its age label does, instead of holding full opacity for a minute past that (#22)
• Shows a "+N more nearby" hint when a busy corridor has more buses on a service than are drawn (#22)
