Read item weight, value and base name through the bridge

Consumers of the legacy ItemTemplate item_wt, item_value and
item_base_name now read getItemWt(), getItemValue() and
getItemBaseName() on template.cacheTemplate.

Parity (offline, scripts/p14.py, 7586 templates): 0 differences in
item_wt, item_value and item_base_name. No value changes expected.

JSON-Refactor-Plan Task 1.4.
