#312212 Robin van Emden: applying some aspects of the patch supplied, should help with php error warnings

added a function for handling the javascript addition in filtered content areas (required for caching filtered content), also required for the new work in mm_asset

improves the external config item

Fixes and refinements include:

* Various views-related fixes
 - Move rendering to flvmediaplayer from flvmediaplayer_views.
 - Use format_xml_elements().
 - Feed view name to rendering.
 - Append node ID as arg to recommendations view urls. This enables the
construction of views with node ID arguments so that recommendations can
be node-specific.
* Fix issues with node-specific configs
 - Ensure data are saved and loaded.
 - Use a node type's registered configuration as default if available.
* Remove flvmediaplayer_extend(), use module_invoke_all() instead.
* Load $node->flvmediaplayer_config in nodeapi's 'load' op.
* Remove 'nid' and 'node' from config array.
* Pass node in flvmediaplayer_extend_fire(). This permits e.g. the
appending of node IDs to view paths.
* Fix hook_menu() implementation (previously didn't use $may_cache
test).
* Various minor code style tweaks.

NOTE: sites will need to run an update to refresh menus.
