"static $node_settings" in _feedapi_store_settings()

From http://php.net/global

A static variable exists only in a local function scope.

Instead of dealing with variable scope issues following approach might be taken.

Introduce an argument "$reset = FALSE" for feedapi_get_settings() like following and reset $node_settings[$nid] if "$reset = TRUE".

function feedapi_get_settings($node_type, $nid = FALSE, $reset = FALSE)
