Implement Cyberdogs gameplay

[cxong]

There seems to be lots of fans of Cyberdogs, some who prefer its gameplay over C-Dogs. It'll be nice if its gameplay can be included in C-Dogs as well.

This is a pretty big feature composing many parts, so this should be split if it is ever undertaken:

• Cyberdogs weapons (Cyberdogs weapons #268)
• Armor (Health pickups #219), buy/sell
• Ammo (Ammo #278)
• Lives (Life powerup, persistent lives #741)
• Auto melee (Auto melee #742)
• Buy/sell weapons/gear between levels (Buy/sell weapons, ammo #739)
• Buy/sell lives, max health (Buy/sell lives, max health #757)
• Upgradable weapons (for the chainguns) (Upgradable weapons #740)
• Health bar (Health bars #26)
• Animated tiles (big fans on ground) (Animated map objects #430, convert drains to map objects, animated tiles will be map objects instead, just like the drains)
• Additional stats in brief/debrief (% enemies, accuracy, enemies killed per weapon type)
• Weapon/ammo/gear pickups
• Move while shooting (configurable), strafing button (Cyberdogs movement options #144)
• Split screen options, including never (Option for split screen never #137)
• No weapon pushback (No weapon pushback #146)
• Rooms with no doors (just open spaces)
• Mission complete message (Mission complete message #198)
• Transition effect between game screens (Transition effect between game screens #199)

Notes:

• Player speed is 8, so quite a few enemies are much faster than the player
• Source code stats are wrong, as the game went through changes
• Armour plus sets 80 health regardless of player max health

Mission maps (partial)

Some notes:

• It feels like most maps are roughly square, although there may be slight differences in size
• Maps are composed of rooms with random number of doorways and random wall sections, similar to C-Dogs
• Objects are placed randomly but never against a wall, however they could block a doorway and can be placed side-by-side to each other
• Random debris (bullet holes, blood) seems to be splattered everywhere regardless of level
• Pickup objectives can appear anywhere
• Destroy objectives only occur in rooms

According to the source code, https://github.com/cxong/cyberdogs/blob/dc536cecae07e1e7361278a2147fd567382bce93/dogs.pas#L479-L483 the map generation params may just be completely randomised

It appears that Cyberdogs is heavily randomised - every mission, including style and objectives, are randomised. Pickups are also randomised, and drawn from the same pool, except a few special items:

• Weapons (powergun, blaster, flamer, chaingun, launcher), equal chance, drawn from the same pool, 4 per level
• Armor - number based on mission (i.e. 1 on mission 1, 2 on mission 2 etc)
• Max armor - 2 per level
• Lives - 2 per level

Note that pickups are doubled when there are two players
