Add support for "26" machine type. PlingSystem updates.

Detail:
  ImageName/SysMap - Add support for "26" machine type
  Components/ROOL/PlingSystem - Remove manual specification of All32 machine type for BASIC - would have resulted in code which isn't ARMv2 compatible. Remove 350 version of TaskWindow - the 310 version should be fine for all OS versions that PlingSystem targets. Document why SharedSnd is using the All machine type.
Admin:
  Tested with PlingSystem build


Version 6.90. Tagged as 'BuildSys-6_90'
