add: ITS rules for "monsters/*.xml" files.github/fork/nelson6e65/itstool-fixes

This avoid including unnecesary strings to be translated.
Only the NAME of monster must to be translatable.

Usage:
  Via "-i" command-line option.
    Just run this command:

      $ itstool monsters/monster*.xml -o "monsters.pot" -i "monsters/_monsters.its"

  Using XLink href attribute in *.xml files.
    - Add this line after root node (monsters) to ALL monster files:

      <its:rules version="1.0" xmlns:its="http://www.w3.org/2005/11/its"    xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="_monsters.its" xlink:type="simple"/>

    - Then run:

      $ itstool monsters/monster*.xml -o "monsters.pot"
