Added more files to the Rowley and IAR LM3S demos to test building the newer files and queue sets.

Browse Source 
Made queue function prototypes consistent so xQueueHandle parameters are always xQueue, and xQUEUE * parameters pxQueue.
Likewise make the task API using px for pointers to TCBs, and just x for task handles.
Heap_x functions now automatically align the start of the heap without using the portDOUBLE union member.
Queue.c now includes queue.h.
