Remove Slave run cooldown.

[Tomowolf]

While doing slaverun, after successful run, we get our reputation back to 150, If we lose, we got it back even to 0.
I suggest removing time cooldown, which is 2 hours, and higher the requieqremtn of reputation with slaver guild from 150 to 200.(Before was 160)
This will prevent using many alts with grease guns to make 10 slave runs in hour, with 10 alts with 3 lvl, and promote doing this with 1 alt.
I suggest also bigger reward for a bigger level.

Yeah cooldown will be removed.

But:
- there will be level requirement to take slave run quest (probably 18),
- rewards will be decreased. I've got no time to test it now, so after I make these changes and the server starts I'll require some honest feedback on these: description of how slave run was done and what was the reward. Then it will be balanced.

Done. I guess it can be closed for now.
