Prevent Load more button on activity page from "hot-clicking"

[slaFFik]

On activity directory scroll down the page and click 5 times (or whatever your finger speed is) while the older activity content is loaded. That content will be loaded 5 times (or whatever...), no duplications (that's good), but with artifacts: ​http://screencast.com/t/auZFawEFb (testing on BP Default).

2012 theme and several other have the same effect, so this is not theme specific.

It's a good practice while showing the spinner still block the button/link from more clicks as well while processing the results.

Using BP 2.0 RC-1 and no plugins that modifies activity stream.

Good find. We should be blocking the button, as you note.

Aha, that's what I was referring to in ticket:5212#comment:9 but completely forgot about. Cheers slaFFik.
