Modifying templates for HotA.

Complaints about early encounters are most likely directed at the "default" version of the template currently used in HotA. In version 6lm10a(j), the issue is solved by the absence of roads in free passages, and in my opinion, that is quite enough. Early encounters are only possible in this case if a portal generates next to a road, but this happens within the acceptable range of randomness.

Regarding UTs, I agree with Sanyok. Increasing the frequency of UTs should be done alongside zone restrictions, because generating 2+ UTs in corner/central treasure zones also seems imbalanced.

P.S. Besides 6lm, I would also pay attention to the number of UTs on Diamond (Roads).
