3.21 attack and lightning masteries

[dbjorge]

Description of the problem being solved:

Implements the following attack and lightning masteries:

• Monsters cannot Block your Attacks
• 5% increased Attack Speed per Enemy in Close Range
  • This requires setting both # of nearby enemies config and "at close range" config to apply
• Nearby Enemies are Intimidated while you have Rage
  • Followed the existing example from "nearby enemies are crushed while you have ?a?t? least (%d+) rage"
  • I originally tried to implement this using a more general "while you have rage" entry, but didn't end up getting this to work (I suspect my naive attempt might have been ending up trying to apply while the enemy had rage)
• 60% increased Critical Strike Chance against enemies with Lightning Exposure
  • In order to handle EE correctly, I created a new Condition applied after the EE applicability calculation and based the new mod on that condition, rather than attempting to use a threshold on the base LightningExposure value

Steps taken to verify a working solution:

(using the showcase PR linked below)

1. For Monsters cannot Block your Attacks, the provided build has some monster block configured and the mastery selected; verify that checking and unchecking the mastery impacts double strike damage but not the spells' damage accordingly, and verify that with the mastery checked, double strike's damage does not change when modifying monster block chance config
2. For attack speed per enemy in close range: verify that double strike attack speed is updated when # nearby enemies config is modified and "is close range" config box is ticked, but not otherwise, and that the spells' damage is not modified
3. For Nearby Enemies are Intimidated while you have Rage, verify that ticking and unticking the mastery affects damage appropriately if-and-only-if rage is configured as non-zero
4. For crit chance against lightning exposed enemies, verify that with the mastery allocated, crit chance increases either upon setting WoC exposure config to lightning or allocating EE (but only if an appropriate combination of "Enemy was Hit by X Damage?" config boxes are ticked)
