[Prestige] Merchant Job's Frequent Trades skill effect is unclear

[jimu]

The "Frequent Trades" skill is unclear.

• The title of the skill, "Frequent Trades," suggests the "Next trade available" counter will be reduced
• The description of the skill is "Trade more often," which supports this assumption
• The "Helps" section says "Trade Income" is improved by a percentage, suggesting that the gold awarded for a trade increases.
