/**
*
* 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
*
