Add Plugins Active Installs to core

[dd32]

Since WordPress.org now displays Active Installs inplace of the Download count, WordPress should also present that information.

There's two implementation possibilities:

1. Remove Download count entirely, and replace it with Active Installs
2. Simply display Active Installs as a new item above Downloads

The active Install count isn't exposed through the API yet, however will be made available for this ticket shortly.

Thoughts?

Definitely replace download count with active installs.

Seems like we try to be consistent with .org whenever possible, so I'd be willing to entertain including this in 4.2 as long as we get the associated string changes from %s downloads to %s active installs, etc. done before beta 4 is tagged tomorrow.

Feel free to milestone this once there's a patch :-)

31865.diff​ contains the core alterations needed, the API has been updated.

Can someone review the strings for me? I'm mostly concerned with the seemingly-random capitalisation on the listing screen.

@dd32: The strings look good to me.

In 31990:

Plugins Browser: Replace the download count with the number of Active installs of the plugin.
Fixes #31865
