Update Shell code from Library-1_58

* Now does an OS_SynchroniseCodeAreas before jumping to Shell_Job (and back again)
* Removed the attempted Arthur 1.20 support - it was attempting to support this using the 'X' form of XOS_ChangeEnvironment, except that that SWI name wouldn't lookup on Arthur. Doh!

Version 1.34. Tagged as 'ChangeFSI-1_34'
