fix: don't record various commands in demos

[ThisAMJ]

Also wanted to do sar_hud_order_{top,bottom}, sar_ihud_preset, and sar_fast_load_preset, but macro weirdness scared me off (CON_COMMAND_F_COMPLETION doesn't seem to like the autocomplete func being defined inline) (obvious now that i actually look at what that does)

Newly unrecorded commands:

• sar_hud_order_reset
• sar_hud_set_text
• sar_hud_set_text_color
• sar_hud_hide_text
• sar_hud_show_text
• sar_ihud_setpos / sar_lphud_setpos (CON_COMMAND_HUD_SETPOS)
• sar_toast_setpos
• sar_ihud_modify
• sar_ihud_add_key
• sar_ihud_set_background
• sar_ihud_clear_background
• sar_toast_tag_set_color
• sar_toast_tag_set_duration
• sar_toast_tag_dismiss_all
• sar_toast_dismiss_all
• sar_toast_create
• sar_toast_net_create
• sar_echo
• sar_echo_nolf

Don't merge this yet, I'm going to redo it with less badness

Closing for now, I'll get back to ya (I've been infected with mlugg's ADHD and haven't touched it since I said I was going to)
