Make collectible threads more visually enticing

[wjt]

On a recent build review @saspiers pointed out that collectible threads just sit on the ground with no idle animation, while other items (notably ability powerups and coins) have idle animations and in the case of the powerup has a visual effect behind it clearly suggesting "pick me up, pick me up!"

But threads are just as important as powerups, and more important than coins!

We could add the same "collect me!" effect behind threads, and/or add an idle animation, and/or do something else to draw more attention to them.

(I feel honour-bound to say that in several hours of watching at least a dozen playtesters at Serious Play, I never saw anyone fail to realise they needed to collect a thread.)
