Load BaseClass from the class runes instead of static_rune_baseclass

LoadAllBaseClasses builds one BaseClass per CLASS rune with
rune_is_standard_character_creation (2500-2503; promotions and Pet are
skipped) and caches it. Race.baseClasses picks up the cached objects through
GET_BASECLASS_FOR_RACE. The SQL loader stays until task 2.11.

Value changes: description goes from '' to the rune_dsc class blurb (unread).
All other fields unchanged; final parity before the switch (scripts/p21.py):
4 rows, 0 differences in name, attribute mods, token, health/mana/stamina mods.
The static_rune_baseclass comparator is removed; it would only compare the
JSON with itself now.
