* pandoradb.sql, pandoradb_migrate_20_to_21.sql: Added id_agent field
to tlayout_data. It's needed to give support to nodes in visual
console that represents a whole agent which turns red if any module is
down.
* operation/visual_console/render_view.php: Removed refresh countdown
and selection because it's now done in the page header.
* include/functions_visual_map.php: Some fixes to support id_agent
field in tlayout_data. Also fixed the SQL to check if any module on an
agent is down.
* godmode/reporting/map_builder.php: Update and insert id_agent when
managing a node element.
* include/styles/pandora.css: Added a style to input image elements.
