As requested by Event Horizon, this removes the limit on fireball types. The fixed array has been replaced with a vector and the relevant code updated accordingly. There is also a new version of `stuff_int_list()` to parse ints into a vector.
This also adds bounds checking for explosion animations that are parsed for ship classes, ship types, and asteroids, since previously there was no guarantee that the indexes would be in range.
The logic to handle the `$Fixed Missile Detonation:` flag missed an important case: subsystems with concave hull geometry but without destroyable submodels. The original flag was tested on a bowl-shaped turret, which could be destroyed. However the bowl-shaped engine on the SSG Rahu was susceptible to the same detonation problem. By changing the check to always use the radius, whether obtained from a submodel or from the subsystem, the flag fixes the detonation in both cases.
* Add control_info driver sources
* Properly deal with cockpits and their 'objnum's
* Add driven animation sets to weapons and cockpits
* enumify objnums
The general expectation is that model filenames can be specified as 'none' or '<none>' for no model, but as discovered by no tea, this was not consistent across the code base. For example, `$Model File: none` was handled as expected but `$External Model File: none` was not. This PR makes the handling consistent for all ship, weapon, and shockwave POF files, and also adds some extra checks when models are loaded.
Add `const` to the `eval_enemy_obj_struct` struct so its values aren't inadvertently overwritten. Handle a bit of const-correctness propagation. Also add default member initialization to the struct.
The code has always checked a per-weapon-class value called `lock_fov` when comparing the dot product of a ship to its target to see if it can lock on to it, however the weapon table hasn't ever included a way to set this value; it's always the default value of 0.85. This just adds "+Lock FOV:" entries to aspect/javelin homing missile parsing after "+Seeker Strength:", which will set `lock_fov` as long as the supplied input is between 0 and 360 degrees.
Add some extra logic implied by the `Begun_detonation` flag. Missiles that are homing can have their targets, headings, speeds, and lifetimes changed for various reasons. If a missile has begun detonation, particularly if it is in "detonation limbo" because it is flying across a bowl-shaped turret, we don't want to change any of that. The "detonation limbo" weapon lifetime is only accurate if all of those values remain constant.

For certain calculations involving armor, the `GetDamage` function needs to know if the damage is being applied by a beam so it can apply the calculations with the proper frametime. The parameter was not provided in all cases, so this fixes that.
Follow-up to #1609.
