Follow-up to #4602. Overall the PR was good, but there are a few extra small changes that should go in. In order of priority:
1) The `exitLoop`, `skipMission`, and `skipTraining` functions should check for campaign mode.
2) The `isVisible` virtvar should be changed to a function, because calling it may have side effects. In standard usage, the briefing formula is evaluated exactly once per stage on briefing initialization, so scripts should follow this convention.
3) The `hasGoalsSlide` function should be called `hasGoalsStage`, because "stage" is the common terminology in FSO.
4) Paging out mission messages is already done in `game_level_close` and should be removed from not only the scripting method but the method it was based on.
5) For consistency, unused parameters should use the `SCP_UNUSED` macro.
6) The `isTraining` flag check can be slightly streamlined using the double-not trick.
* Applying directional brightness profile value, disconnected spec flags and made specular light always equal to diffuse light
* Switched over to new command line arguments
* Wire lab up to new lighting controls, and provide backwards-compatible defaults for emissive.
* cleanup unused new function
* make static some functions that can be static
* revise command-line and emissive handling
* handled specular sun depreciation and general removal of specular value handling
* Removed specular light color as a separate value in the uniform buffers.
* cleanup of leftover/post-rebase specular references
* further post-rebase repair of light flags command line and leftover specular
* move techroom/selection/breifing 'room' lights to a common function and
augment lighting setup for current rendering
* fixed some mishandling of lighting modifiers.
* Addressed code clarity and comments from review
* Documentation (+6 squashed commit)

* Differentiate var names
add `getDirectiveLines` and `setPosition` script functions
properly error if trying to set a HUD gauge name
remove the unneeded `Directive_frames_loaded` variable
improve accuracy of SEXP help for HUD gauge operators
* Add drop shadows to HUD text
* Add drop shadow to reticle
* Add control to toggle Drop Shadows
* Double render reticle shadows
* Use gauge_color instead of creating a temp var
* Add shadows to ETS gauges
* Set shadow default to false and adjust formatting
* Restore numbering for controlsconfig
Protects `Fiction_viewer_active_stage` if it reads a stage of -1 (it would have thrown a vector access error because the index is out of range). Also, given a lot of other scripting functions have additional built in error checks, I just added those to the fiction viewer functions.
* Add Animation Instance Flags
* Add SEXP barebones
* Unify and simplify animation parsing
* Clean up animation calling and use new animationlist api
* Add missing break
* Add Lua access to a ship's Scan Time
* Disallow writing to the shipclass value
* Remove ship access in favor of shipclass access. Resolve read only issue.
* Cleanup and error if script attempts to set Scan Time
* Whoops. Still need to get the shipclass.
Previously the persistent object sound management code would attenuate all script-assigned sounds by engine strength, and would not play them at all if the engine was off. This fixes the code to only apply that logic if the sound is in fact and engine sound.
The movie player code was missing some important functionality, in particular:
1) There was only one timing method to get real-time elapsed time, which was not suitable for pausing or time compression
2) There was an improper cast for the FPS property, causing a script error
3) The `getSeconds` method lost precision during casting
This patches those deficiencies.
The two `VIRTVAR`s for Orientation in subsystems and submodel instances do the same thing, but did not have the same code - in particular, the subsystem version did not update the subsystem angle and turret angle. This syncs them up.
