Spawn crates /w Warheads & minor crate improvements

[Starkku]

Spawn powerup crate

• Warheads can now spawn powerup crates of specified type(s) on their impact cells (if free, or nearby cells if occupied something other than a crate) akin to map trigger action 108 ('Create Crate').
  • SpawnsCrateN where N is a number starting from 0, parsed until no key is found can be used to define the type of crate spawned.
  • SpawnsCrateN.Weight is a number that determines relative weighting of spawning corresponding crate type vs. other listed ones (0 is no chance, higher means higher probability) defaulting to 1 if not defined.
  • SpawnsCrate.Type/Weight is an alias for SpawnsCrate0.Type/Weight if latter is not set.

In rulesmd.ini:

[SOMEWARHEAD]            ; Warhead
SpawnsCrate(N).Type=     ; Powerup crate type enum (money|unit|healbase|cloak|explosion|napalm|squad|reveal|armor|speed|firepower|icbm|invulnerability|veteran|ionstorm|gas|tiberium|pod)
SpawnsCrate(N).Weight=1  ; integer

Crate improvements

There are some improvements on goodie crate logic:

• The limit of vehicles a player can own before unit crates start giving money instead can now be customized by setting UnitCrateVehicleCap. Negative numbers disable the cap entirely.
• FreeMCV setting is now actually respected and can be used to disable the forced unit selected from [General] -> BaseUnit that is given if player picks a crate and has enough credits but no existing buildings or BaseUnit vehicles.
  • The previously hardcoded credits threshold that must be passed can also now be customized via FreeMCV.CreditsThreshold.
• It is possible to influence weighting of units given from crates (CrateGoodie=true) via CrateGoodie.RerollChance, which determines the chance that if this type of unit is rolled, it will reroll again for another type of unit.

In rulesmd.ini:

[CrateRules]
UnitCrateVehicleCap=50         ; integer
FreeMCV=true                   ; boolean
FreeMCV.CreditsThreshold=1500  ; integer

[SOMEVEHICLE]                  ; VehicleType
CrateGoodie.RerollChance=0.0   ; floating point value, percents or absolute (0.0-1.0)

I love this and thank you for making this!

money:		ok
unit:		ok
healbase: 	ok
cloak:		ok
explosion:	ok
napalm:		ok
squad:		money
reveal:		ok
armor:		ok
speed:		ok
firepower:	ok
icbm:		ok
invulnerability: displays armor p-up animation, nothing happens
veteran:	ok
ionstorm:	nothing
gas:		ok
pod:		nothing
darkness:	crate does not spawn

Crates spawned on the water are money, as normal.
Squad does't work and it shouldn't i think.
Invulnerability displays armor power up anim, nothing happens.
Pod no animation, no effect.

I would suggest to default crate to moneycrate if crate type is not supported,
missing or garbage is written like here:

SpawnsCrate0.Type=randomtext
SpawnsCrate0.Weight=1

I would like to also suggest to default to moneycrate not working powerups and unlist them from documentation.
Tested with ra2yrbf

I will test it in mp soon.

CrateType not supported is treated as if nothing was parsed.

darkness not working was a parsing bug I fixed.

Many Powerups not working is an existing problem that I have not addressed with these changes.

This looks good besides a few tiny inefficiencies in parsing.
