Subject: [PATCH] libpredict: predict incoming heals for built-in click casting
 (#44)

Built-in click casting drives the cast through secure frame attributes,
bypassing the CastSpell/CastSpellByName/UseAction hooks that populate
spell_queue -- so the heal-prediction lookup in the SPELL_START_SELF
handler missed and no incoming heal showed.

Populate spell_queue from the cast's own rank-specific spellId (via
C_Spell.GetSpellName/GetSpellSubtext) right before the cache lookup, so
prediction works regardless of how the cast was initiated. Deriving the
rank from the actual spellId also fixes stale-rank lookups when a prior
keybind cast left a different rank of the same spell queued.
