Add start card rule affecting all heroes.

Resolves #80 .

Note: Haven't gotten around to testing this. Feels like it should work, but can't confirm.

@jimconner In case you happen to want to play with this, feel free to merge if it checks out. Else, I can try to test in the next couple of days.

Tested with the following ruleset.

var guardianCards = new List<Rules.StartCardsModifiedRule.CardConfig>()
                {
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Whirlwind, IsReplenishable = true },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Zap, IsReplenishable = false },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.CoinFlip, IsReplenishable = false },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Freeze, IsReplenishable = false },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Fireball, IsReplenishable = false },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.ReplenishArmor, IsReplenishable = true },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Heal, IsReplenishable = false },
                };
            var hunterCards = new List<Rules.StartCardsModifiedRule.CardConfig>()
                {
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.PiercingSpear, IsReplenishable = true },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Zap, IsReplenishable = false },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Speed, IsReplenishable = false },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.HunterArrow, IsReplenishable = false },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Fireball, IsReplenishable = false },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Heal, IsReplenishable = false },
                };
            var sorcererCards = new List<Rules.StartCardsModifiedRule.CardConfig>()
                {
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Whirlwind, IsReplenishable = true },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Zap, IsReplenishable = true },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Fireball, IsReplenishable = false },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Fireball, IsReplenishable = false },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Fireball, IsReplenishable = false },
                    new Rules.StartCardsModifiedRule.CardConfig() { Card = AbilityKey.Heal, IsReplenishable = false },
                };

            var startCardRules = new List<Rule>
            {
                new Rules.StartCardsModifiedRule(new Dictionary<DataKeys.BoardPieceId, List<Rules.StartCardsModifiedRule.CardConfig>>()
            {
                { BoardPieceId.HeroGuardian, guardianCards },
                { BoardPieceId.HeroHunter, hunterCards },
                { BoardPieceId.HeroSorcerer, sorcererCards },
            }),
            };

            var startCardRuleset = Ruleset.NewInstance("StartCardRuleset", "New starting hands for Guardian, Hunter and Sorcerer", startCardRules);
            registrar.Register(startCardRuleset);

Changes are not having any effect at the moment. I'll see if I can work out why.

I found the issue that was stopping this working and have pushed another commit with the fix.

Should all be good to merge now.
