Basic Profile visibility - markup enhancements

[hnla]

A few adjustment to markup before 1.6 drops and can't easily change.

• Remove orphaned 'label' element in parent .field-visibility-settings.
• Add fieldset and legend to replace label for text 'who can see this field' in register.php | profile/edit.php
• Change settings toggle to 'p' tag - text/pcdata not in non semantic agregator (div could be added back around 'p' tags but achieves little other than extra styling hook but bloats markup)
• Adjust bp-xprofile-template 'bp_profile_get_visibility_radio_buttons()' to add labels & 'for' atts
• Minor changes to global.js to hide radio buttons on load before running toggles and to contrast anchor toggles and radios with fadeOut & slideDown respectively to smooth out transitions (slightly less jerky)

Meh. :)

Thanks for the patch, looks good.

(In [6051]) Markup enhancements for profile visibility

• Removes an orphaned 'label' element
• Replaces some 'label' elements with 'fieldset' and 'legend' for greater accuracy
• Changes some div elements into paragraphs, so that text does not appear outside the context of semantic elements
• Modifications to the visibility options toggle JavaScript, for better differentiation and smoothness

Fixes #4224
