/**
 *
 * Function : profile_load
 * @parameter App    $a
 * @parameter string $nickname
 * @parameter int    $profile
 *
 * Summary: Loads a profile into the page sidebar.
 * The function requires a writeable copy of the main App structure, and the nickname
 * of a registered local account.
 *
 * If the viewer is an authenticated remote viewer, the profile displayed is the
 * one that has been configured for his/her viewing in the Contact manager.
 * Passing a non-zero profile ID can also allow a preview of a selected profile
 * by the owner.
 *
 * Profile information is placed in the App structure for later retrieval.
 * Honours the owner's chosen theme for display.
 *
 * IMPORTANT: Should only be run in the _init() functions of a module. That ensures that
 * the theme is chosen before the _init() function of a theme is run, which will usually
 * load a lot of theme-specific content
 *
