Working Slave Market in Port Telvannis for Tamriel Rebuilt

Allows you to buy slaves at Port Telvannis Slave Market from Tamriel Rebuilt. I felt it's a bit underwhelming to see a slave market and having no way of interacting with it, I'm sure TR crew sooner or later will get back to it's older content, but it seems they work on Narsis currently, so I've made a quick hotfix to use in a meantime.

I have no idea how scripts work and I have no programming knowledge at all, but I've simply looked up how the scripts for Mundrethi Plantation are written and reverse engineered that like a monkey to work on a slave trader in Port Telvannis. It works, and hopefuly I didn't mess anything up in the process. You can now buy any of slaves present at Port Telvannis Slave Market for 1000 septims and free them if you want.

I'll be uploading an addon for Fligg's Slave Mod soon, working Port Telvannis market should work very well with that mod. Flarex16 has uploaded a fantastic mod made by Fliggerty, allowing you to claim slaves you've freed from their captors / bought on a market. It's a very cool game mechanics, because it basically lets you turn slaves into your trusty companions. There are very cool features in the mod, allowing you to talk, share food and drink with them and most importantly from a gameplay point of view - share equipment with them. This allows you to give them cool outfits, and help you with holding all the items you loot on adventures you do together.

The only problem with Fligg's mod is that it seems to be quite old (after all, it's a reupload) and it doesn't work on the Mainland (I think some features may be working, but definitely not Companion Share letting you to give slaves outfits and items).

The mod works on OpenMW49 I'm using, but for some reason by buddy who uses vanilla game + code patch doesn't have buying dialog working. I don't know why, but I suspect it might be related to the order in which mods are loaded.
