HasAuraType condition does not parse placeholders.

Recently, support for placeholders for the aura auratype parameter was added. However, there is no way to dynamically check for an aura type as the HasAuraType condition does not parse placeholders.

Example:

AuraType_apply:
  Skills:
  - skill{s=AuraType_test;aura_type=1} @self

AuraType_test
  Skills:
  # Apply Aura
  - aura{d=40;name=Testing;auratype=<skill.aura_type>}
  # Check if AuraType present
  - message{m=Has this Aura Type already!} ?hasauratype{type=<skill.aura_type>}
  - message{m=Control} ?hasauratype{type=1}
