* minor fixes
* not extern
* break out chat message data into a table
* address some feedback
* return empty strings if not in multi
* use GetChannelByUser() instead
* once more with feeling
* correct documentation
Turn `Parse_names` into a vector and add SCP_string overloads of ship registry functions. Refactor calling code to use registry as appropriate. Remove an unused overload of `mission_parse_get_parse_object`.
* Create the ingame options game state
* Base working version of in-game options
* Cleanup + Optimization
* Localization pass
* more cleanup + documentation
* tooltips on option hover
* documentation and better inbounds check
* match case
* format strings instead of direct strings
* unused parameter
* address feedback
* localization id conflict with master
* Add this line back in
* pass the new option flags as well
* resolve xstr id conflict
1. Fix the item ID indexing on the popup submenus and make sure they correspond with the ship dropdown menu
2. Remove the "player start" popup menu option as it has very limited utility and was already removed in qtFRED
3. Reduce a bunch of casts by using more appropriate popup menu types
4. Actually place an object in the mission when one is chosen from the popup menu
Also:
1. Remove the `Default_player_model` variable as its use is redundant
2. Remove unused arguments of `create_player()`
This refactors the ship registry and the OSWPT struct to store data as indexes rather than pointers. This is a prerequisite for making these collections dynamic in the future. See also #5800.
This advances the versions for Clang to 16 and GCC to 13 along with
fixing any warnings these new versions are detecting now.
The new image versions also include Vulkan so the additional workflow
step for installing that is not necessary anymore.
1. use `SIZE_T_ARG` instead of `"%lu"`; should fix format warning in #5780
2. since `HeapAllocator::checkRangesMerged()` has no effect unless running in debug, `#ifdef` out the function; should fix CI warning in #5778
Some of the `frand_range` calls were used for integer calculations, so we can use `Random::next` now.
This also reduces the number of C-style casts in the codebase.
