Add support for "Price Of Power" (Lich Ascendancy Notable)

[majochem]

Description of the problem being solved:

• Add support for "Price Of Power" (Lich Ascendancy Notable)
  • Non-channelling Spells consume Power Charges to deal 25% more Damage

Notes:

• Might want to introduce some kind of "charge sustain" logic in the future, but that goes too far for now I think

Steps taken to verify a working solution:

• Mod parsed correctly
• Damage bonus is limited to non-channeling spells
• Requires minimum 1 "removable" Power Charge
