Update for compatibility with WordPress 3.5

In 1.0.4, Private BuddyPress adds its settings options to the Privacy section of the Settings menu, which has now been removed in WordPress 3.5. I have moved the settings from the Privacy section to the Reading Section (where the settings formerly in Privacy were moved as well). 

I also bumped the version number from 1.0.4 to 1.0.5.
