Print Area Danger Warnings When Walking Over Entry Portal

[Doctornull]

Right now, you get a (mildly cryptic) message about how dangerous an area is when you enter it, by which point it's potentially too late to leave. It would be nice if the entry portal tile gave the warning, so the player could make an educated choice about which areas to delve into.

The messages would change as you level up, relative to the destination's danger level:
- "This area looks MUCH too dangerous for your current abilities!"
- "This area looks challenging for your current ability level."
- "This area looks like something you can handle."
- "This area looks like it won't be much of a challenge for you."
- "This area looks too easy for you."

This would be mostly helpful to new players, as veterans are long spoiled.
