Don't show BP-Wizard permalinks panel if we have pretty permalinks

[cnorris23]

During a new installation of BP, the permalinks panel is shown regardless of whether or not pretty permalinks are already in use. This can cause confusion if the user already has them set.

Nice idea

The $wp_rewrite global is already there, so use that instead.

(In [4291]) Only show permalinks panel during install if not already in use. Fixes #3178, props cnorris23

(In [4293]) Revert r4292:4290. See #3178

I decided to revert this commit as it had the unintended consequence of making the "Permalinks" panel disappear after they were set in the install. This looked a bit jarring. A better solution would be to improve the text on the permalinks panel to make it clear that they've already been set. Most of the the upgrader screens' text need some love, so it's probably worth getting them in one go.

I remember running into this when I was doing something with the pages panel. Unfortunately, I can't remember how I fixed it. I'll play with it tonight, and if I can't come up with a solution that's not hacky, I'll write up a patch with alternate text.

Finally got to this. I spent some time trying to figure something out, but there's no easy way that doesn't require a temporary database option or another cookie. It's just not worth all that. Besides, it can't hurt to give admins another chance to get the pretty permalinks of their dreams :)

+1 for this solution. I'm going to tweak the wording a bit and then throw 'er in there. Thanks, cnorris23.
