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:

• [x] Cyberdogs weapons (#268)
• [x] Armor (#219), buy/sell
• [x] Ammo (#278)
• [x] Lives (#741)
• [x] Auto melee (#742)
• [x] Buy/sell weapons/gear between levels (#739)
• [x] Buy/sell lives, max health (#757)
• [x] Upgradable weapons (for the chainguns) (#740)
• [x] Health bar (#26)
• [x] Animated tiles (big fans on ground) (#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)~
• [x] Weapon/ammo/gear pickups
• [x] Move while shooting (configurable), strafing button (#144)
• [x] Split screen options, including never (#137)
• [x] No weapon pushback (#146)
• [x] Rooms with no doors (just open spaces)
• [x] Mission complete message (#198)
• [x] 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

Estimating from the minimap size, maps are 100x100

[cxong]

Demolition bonus is basically just the score you get for destroying items It is equal to the health of the objects https://github.com/cxong/cyberdogs/blob/dc536cecae07e1e7361278a2147fd567382bce93/game.pas#L692-L704 However this bonus, divided by 10, goes towards the end of level bonuses (whose calculation is unknown)

[cxong]

The way cyberdogs does demolition bonus is somewhat incompatible with C-Dogs. C-Dogs gives score for damage inflicted on enemies, but not objects, unless that object is an objective, in which case a flat score is given when it is fully destroyed. However Cyberdogs adds score by damage, as if they were C-Dogs enemies. As an approximation we can make Cyberdogs objects all objectives, however we'd need to add a way of customising score so that you get more points for tougher objects - i.e. customise OBJECT_SCORE.

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
