* Add ability for a Lua sexp parameter to require a 'parent' parameter
* Add dockpoint as a return type
* variable conflicts
* var name
* qtfred
* address feedback
Several items here:
1. Patches several category and subcategory validation checks (comparisons to -1 rather than _NONE) that were missed in #4965.
2. Adds sanity checks to both built-in operators and scripted sexps to ensure categories and subcategories are consistent.
3. Deconflicts several built-in sexps that had inconsistent categories.
The inconsistent operators were:
* script-eval-string
* set-wing-formation
* get-ets-value
* turret-get-primary-ammo
* turret-get-secondary-ammo
* get-fov
Follow-up to #4965 and #4995.
This adds a "clear-debris" SEXP with a new system for declaring SEXPs
outside of sexp.cpp. This makes it easier to keep code modules self
contained since they do not need to export previously private
functionality just for having missiong being able to interface with it.
This is mostly a proof-of-concept which only supports basic parameter
types (booleans and integers).
