FreeHL/SH: Weapon prediction improvements
FreeCS: Added back in basic bullet-penetration/wallbanging. It doesn't do anything but go through 4 layers. I made a testmap on which I'll start document 1.5 wallbanging behaviour.
- Added early Rewolf Health/Armor HUD variants
- Added original scoreboard from the early Half-Life versions for valve/scihunt/rewolf
- Fixed some skybox behaviour to only apply to BSP30
- Changed the env_message and game_text display to use "creditsfont" instead of the conchars
- Tweaked damage radius and prediction for some entities and weapons
- Added world_items
- Added item_healthkit
- Added item_battery
- Fixed level transition logic
- impulse 101 now fills up health and armor/suit in mod valve
- Some tweaks to Damage_Apply so that healing can be performed without funky visuals
- Added stub monsters for valve/rewolf that'll soon support scripted sequences
- Tweaked chat system to get rid of quotation marks around messages
- Added support for changing the window caption to reflect the mod you're playing
- Lots of small little things in terms of cleanup
