Richard Barry ab964f3c9d Updated to V4.0.5
+ Introduced API function xTaskResumeFromISR().  Same functionality as
	  xTaskResume(), but can be called from within an interrupt service routine.
	+ Optimised vListInsert() in the case when the wake time is the maximum 
	  tick count value.
	+ Bug fix:  The 'value' of the event list item is updated when the priority
	  of a task is changed.  Previously only the priority of the TCB itself was
	  changed.
	+ vTaskPrioritySet() and vTaskResume() no longer use the event list item.
	  This has not been necessary since V4.0.1 when the xMissedYield handling
	  was added.
	+ Lowered the PCLK setting on the ARM9 STR9 demo from 96MHz to 48MHz.
	+ When ending the scheduler - do not try to attempt a context switch when
	  deleting the current task.
	+ SAM7X EMAC drivers:  Corrected the Rx frame length mask when obtaining 
	  the length from the rx descriptor.
