Very slightly restyled NPC dialog windows.

This may be a preferential thing, and I expect it may be debated, but I was slightly bothered by how NPC dialogs were currently being displayed. The problem I had with them was that the character who was speakings name was inline, and on every new window I was reading their name first and it was breaking the flow of the conversation. To solve this I've separated their name from their dialog and bolded it to set it apart more distinctly.

Here are screenshots:

The way I did it may not be the best way to, and I recommend any and all critiques. At first I had the two styles be configurable (in talker.txt you could set a flag for whatever style) but I've decided to simplify it and just force this style. I've tested in multiple resolutions (even the lowest possible) and it displays properly in them all.
