Read item user power actions from the cache template

The magical name color check and loadTemplateEnchantments read
getItemUserPowerAction(). The list keeps duplicates, so the baked-in
enchantments collapse a repeated power to its last entry, as the legacy
HashMap did; applying it twice would add its name to effectNames twice and
double its share of calcMagicValue.

Offline parity (p15e.py, 7586 rows): 0 differences in the lists (power and
arguments, in order). Duplicates exist only on 81 RUNE templates (mob,
guard and siege runes, plus discipline rune 3006 Blade Weaver with two
identical AMBIDEXTERITY entries); none on ITEM or DEED.

Value changes: none. Enchantments are now applied in file order instead
of HashMap order; effects are keyed by effect id and calcMagicValue is a
sum, so the result is the same.
