* The switch '-stb' has existed for some time but is a bit obtuse, renamed to '-continue' (though -stb is still accepted as an alias).
* Added support for BootFX module, via switch '-progress start,range' which will scale the work done and work yet to do into a percentage and pass it to the BootFX module (intended to track boot progress).
* Trimmed out old switched out repeat command code that ran in SVC mode.
* Eliminate last trace of Support011 library, was only using the control terminated version of strlen() which is in ConfigLib (now linked against).
* Const qualifiers added to command handlers.

Version 1.44. Tagged as 'BootCmds-1_44'

* Recreated from fragments
* No longer creates two resource areas (one for Repeat, one for messages) since RESGEN can put many files into one area
* No longer does a ResourceFS register in the ROM case - the resources phase now exports both Repeat and messages directly into the messages module
* Corrected error number for BufOFlo (was using the token number!)
* Used newly allocated error base for all other errors
* Internationalised "Can't claim memory" in Repeat
* Fixed a couple of compiler warnings

Version 1.43. Tagged as 'BootCmds-1_43'

Note the code for Appslot and Appsize is probably sufficiently similar
to allow Appsize to be deleted or aliased with Appslot.

Version 1.30. Tagged as 'BootCmds-1_30'

Loadcmos will now only load 240 byte configs on machines <= 370,and
will fault configs if the local Boot$OSVersion doesn't match that
stored at the end of the file,or if the checksum is wrong.
Most of the Loadcmos stuff is stolen from the old bootsequence util of
the same name.
Added 2 new error messages to the Messages file.

Version 1.29. Tagged as 'BootCmds-1_29'

Changes from KJB to stop the C99 compiler getting upset about BOOL

Version 1.28. Tagged as 'BootCmds-1_28'

Detail:
  The 'X' command has existed for a long while as a transient utility in the
  !Internet application. I have impemented it as a CLI command in this module
  to reduce FS access required to use it. Note: this version of X implements
  the extended functionality of placing any suppressed error message into the
  system variable "X$Error" (if not already set).
Admin:
  Tested on RiscPC.
