Adds a swordsmaster class to the game.

CHANGELOG

1.6.0

 - Added a new talent tree, Technique/Fencing which has defensive talents related to parrying.
 - The talent Web of Steel has been moved from Swordsmanship to Fencing. It's place in the Swordsmanship tree has been taken by a new talent, Vorpal, which gives Physical Power and Armor Penetration.
 - The talent Crescent Sweep has been reworked. It deals more damage, inflicts bleed, moves before attacking, no longer allows swapping places, and has a cooldown. It's usage as a spammable movement talent for swapping places has been filled by the new Mist Step talent on the Fencing tree.
 - Lightspeed Draw can now attack enemies adjacent to any tiles you pass through in addition to enemies that you pass through directly. These additional targets count when determining whether you can use Lightspeed Draw or not. It still can only hit one enemy per tile you travel through though.
 - Fixed Swordsmanship not functioning for daggers
 - Fixed Swordsmanship to not permanently replace a weapon's strength damage mod with dexterity
 - Harrying blows no longer requires your spring attacks to hit the target; instead it only requires that you attempt them.
 - Harrying blows's finishing blow now bypasses evasion/repulsion talents that the target possesses
 - Harrying blows's finishing blow no longer ignores ALL armor and resistances. It ignores 50% of the target's resistances, and has set bonus armor penetration.
 - Spring Attack now functions immediately when activated instead of only after an action is performed after it is activated.
 - Surgical Strikes's stun and interference effects are now separate (so you get the full stun regardless of what the target does on its next turn). It's cooldown has also been increased from 6 to 8.
 - Added clarifying text to the descriptions of Will to Live and Unfetter to give a better idea of how effective they are when leveled up without requiring arithmetic.
 - Buffed Spring Attack stamina restoration
 - Cunning/Tactical is once again locked by default
 - Added translation support to timed effects

 - Fixed bug with pre-use talent for swordsmanship talents when npc does not have an inventory

 - Added a new talent tree, Technique/Two-handed Bladework, which serves as a Dexterity-based replacement for Technique/Two-handed Assault
 - As it has now been replaced, Technique/Two-handed Assault has been removed from the Swordsmaster class.
 - Cunning/Tactical is now unlocked by default

 - Lightspeed Fatigue duration changed from 40 turns to a lower value which is based on effective talent level
   - (with 1.3 mastery: 24, 21, 18, 16, 14)
 - Lightspeed Fatigue now increases stamina cost of Lightspeed Draw linearly instead of quadratically.
   - (20 -> 40 -> 60 -> 80) instead of (20 -> 40 -> 80 -> 160)
 - Removed cooldown from Spring Attack, making it fully toggleable.

 - Changed Moving Target to reduce direct damage taken by 30% instead of giving 15% all resist.
 - Buffed pin resistance of Slippery to 100% from 50%
 - Buffed movement speed granted by Slippery to 50% from 20%
 - Spring Attack once again restores stamina when wielding one-handed weapons
 - Lowered the maximum number of attacks per turn at ETL 5 for Spring Attack from 3 to 2
 - Fixed typo in Harrying Blows description

 - Fixed logic of projectile selffire to correctly function as indicated by comments (for web of steel)
 - Fixed Vapor Blade knocking back even when it misses

 - Swordsmanship now completely exchanges strength scaling for dexterity scaling on swords instead of giving -100% str mod and +100% dex mod
 - Fixed bug that prevented critical hits from occurring (oops!)
 - Unfetter and Never Give Up now have stamina costs
 - Harrying Blows fixed to only require Spring Attack to hit once per global turn instead of once per target's turn
 - Lightspeed Draw now has a fixed cooldown.
 - Spring Attack now only restores stamina if you are wielding a two-handed weapon
