Fixes two bugs:
- Attract mode carrying over to gameplay if an attract
demo is allowed to finish without interrupting it
- Credits ending after the first replay ends
- This was causing Aquatic Cathedral and Aqua Tunnel staff
replays to get confused for one another
- Because for both RR_AQUATICCATHEDRAL and
RR_AQUATUNNEL, the first 8 chars are RR_AQUAT
- Now uses the lump id directly instead of the name, which
entirely circumvents the problem
- Fixed:
- Time Attack menu "Replay Staff" option
- Attract mode
- Credits
- Remove CV_NOSHOWHELP, so the config file can load
- Do not stealth set the cvar, so it is not dependent on
order of operations of config loading and challenge
loading
