Make font for players names more legible

Make font for players names more legible:
Specifics:
This will improve the following aspects of the site:
- * The list of players names and names in the game log needs to be more legible
Specifics:
- * Yellow is currently the hardest color to read, because it's a light color on a white background.
* Better font already exists in the text used for army numbers. A thin black outline offsets the army numbers from the background
* The same black outlining could easily be applied to the names in the "Players" list, and all uses of those names in the game log
This will improve the following aspects of the site:
- * Text will be easier to read
* The same text could be used in a grease monkey script where items other than the players' names are colored.
