New character: Zafira

Zafira is a new merchant, she appears at the portal during the night to sell illegal objects, and unusual (including new type of equipment. I don't know if I'm gonna add them next update though, it's not required yet)

Like other merchant, she is here to make business but she should also have "content" in the future.

In short term I make content for Main girls in priority, next update should focus on Fraka as you voted. I just add some extras for the future (also because Fraka has a quest where you have to talk to every girls so I had to add her now)
