template_unit_cavalry_melee.xml template_unit_cavalry_ranged.xml
do little more than add a health value and a visible class and are thus not particularly useful. This patch removes them. Advantages are:
- meaningful values are defined in a single template, rather than arbitrarily scattered over two levels;
- citizen cavalry templates are more parallel to champion and hero cavalry templates, which don't have *melee* or *ranged* either;
- shorter template file names.
