Collapse Unused Sub-Panels

* Greatly decreases processing required to render the page.
* We don't retrieve information for hidden sub-panels. Users can expand them as they desire.

Configuration change in config.php or config_override.php:

// Always hide subpanels when a user views a detail record
$sugar_config['hide_subpanels'] = true;

//When a user first visits a detail view hide all subpanels for a
module. Then whatever subpanels are opened in that module stay open
throughout the session regardless of what the record id is.
$sugar_config['hide_subpanels_on_login'] = true;
