moodle-tool_mergeusers - added special case for table my_pages

   * if more than a record per user appears in this table, user's MyMoodle
     is not seen correctly.
   * best option is omitting this table from being processed.
moodle-tool_mergeusers - renaming README.txt to README.md

    * this helps to see the MD format of the README file.
    * when uploading a new version on Moodle.org, the site allows you to rename the
      file from README.md to README.txt. That's not a problem ;,-)
