Especially for mobile, we need to signal that the button press was recorded.
@shane-tomlinson - I've added styles and a loader.gif asset, but wasn't sure what buttons this should be applied to or which .js file to implement that functionality in. All that really needs done is to apply a loading class to the button
spinner looks good in train-2012.07.06 when applied with dev tools. Leaving this issue open to actually make use of it where appropriate.
Okay, I've been using current dev with PR GH-2214 on multiple desktop browsers and I do see the spinner appear when clicking through buttons. I'll get to mobile later. Offhand, with a fast browser on a reasonable speed connection, it's a bit of a distraction, but I'll let other folks kick the tires, and see if they think the same.
