Added Help/HTML files written in Engilish.
They will be installed in asir library directory.
'OpenXM/lib/asir/help' is a symbolic link to help-eg.
If LANG is not set, then 'help' refers to 'asir/help'.
If the value of LANG begins with "japan" or "ja_JP", the 'help'
refers to 'asir/help-jp'.
If LANG is set but the value of LANG does not begin with
"japan" or "ja_JP", the 'help' refers to 'asir/help-eg'.
