beta feedback - add more wc options

- splash_screen (boolean for whether to display splash screen at startup)
- player_selection:dialog|prompts

Also moves the font and window manipulation stuff in defaults.nh
further down the file, so that a tty users doesn't have to wade
through it all to find the character adjustment samples.
