Corrected Query Error In Users.php

User.php, specifically the findAll method was prefixing the first query paramter for 'roles' with '&' rather than '?'.  This was causing the query to be ignored and all users returned regardless of what roles were specified.
Corrected Missing Sideload & Iterators

Views.php execute method was not passing sideload and iterators to the Http:prepare method.  This was causing pagination params to be ignored and page 1 was always being returned.
