Toggle All link on its own line

This is a request just to change the display of the Toggle All link that appears when krumo debug data is displayed. Currently, the first line of text that is echoed along with a krumo call will be displayed right along side the Toggle All link:

![ToggleAllNoBlock](https://f.cloud.github.com/assets/4011193/432260/5a48b4c6-ae9f-11e2-914f-dd2cfb492c80.PNG)

But giving `.expand` block display and a little bottom margin provides some nicer spacing:

Also included in this branch are commits from [Pull Request #8](https://github.com/Seldaek/php-console/pull/8) regarding checking for HTTP auth since I neglected to put those in a separate branch, but of course I hope those changes are still being considered.

Hey, I just wanna say again that I appreciate all the helpful feedback and letting me participate in this excellent project. So yes, for your consideration...
