 - tidied up Wimp08s
 - Added optional use of kernel lock for Wimp_ClaimFreeMemory, controlled
   by KernelLocksFreePool in Options (currently true for Ursula only)
 - restricted max size of Wimp Sprite Pool dynamic area to 16M (controlled
   by WimpSpritePoolMaxSize in s.Memory) to avoid wasted address space on
   large memory machines

Made the Wimp always call the postfilter when returning from Wimp_StartTask, rather than only if the child didn't Wimp_Poll. Also ensured that nothing untowards happens if the filter tries to claim this apparent "null event".

Stopped cursor jumping to top left when a task was killed outside the desktop (eg *RMKill ShareFS at the F12 prompt).

Hourglass depth now incremented by 1 between calls to Wimp_Poll; effect is to automatically display hourglass whenever applications hog the CPU, irrespective of whether they already display the hourglass themselves or not.

Hourglass is automatically smashed before any Command Windows are displayed
so that output-generating single-tasking programs are not forced to show the
hourglass due to the behaviour described above.

Made options files specify any text wanted after the module version number.
Auto-fronting iconbar now returns to previous position rather than back, so
it interacts with Shift+F12 better.
