Custom Tabs 1.6.3

I have added user criteria so that you can have more control over the tab user permissions.

I have added the options to apply inline CSS to change the color and style of the tabs and child links and also open tab/link in new window and nofollow.

The attributes for the main tabs are applied using preg_replace which I don't like but couldn't find a cleaner method so if someone knows a better approach, please let me know.

NOTE: Updating to this version requires re-applying the user group permissions.
