[Ecls-list] Changes

[Juan Jose Garcia-Ripoll]

* Visible changes:

 - EXT:PROCESS-COMMAND-ARGS now allows for a default rule.

 - Variable EXT:*HELP-MESSAGE* and EXT:+DEFAULT-COMMAND-ARG-RULES+ exported.

 - C:BUILD-PROGRAM now uses a unique prefix for the initialization function,
   init_ECL_PROGRAM, to avoid collisions when both the program and a component
   have the same name:
	(C:BUILD-PROGRAM "ls" :lisp-files '("ls.o"))

* Contributed code:

 - New examples: cmdline/ls.lsp

The manual now contain reference pages for the command line processing
functions:

If something is not very clear, please write me a note.
