Those functions were platform dependent and user has no control over the file created. They have been removed from raylib and just moved to `core_storage_values` example.

This example requires a complete remake to be more clear. Also current quaternion maths could have issues.

Disable color vertex attribute if not provided by mesh

Simplified example

REDESIGNED: `LoadDirectoryFiles()`
ADDED: `LoadDirectoryFilesEx()`
REDESIGNED: `LoadDroppedFiles()`
ADDED: `IsPathFile()`

This BIG BREAKING change simplifies the functions and gives more control to the user:
 - A new `struct FilePathList` has been added to avoid exposing complex pointers.
 - User is responsible of memory loading/unloading
 - Filepaths loading support recursive directories and file extension filters

RENAMED: `ClearDroppedFiles()` to `UnloadDroppedFiles()`

`physac` is available on its own repo

This feature is still under consideration/testing and it doesn't work properly, at least the Delay Effect processor.

WARNING: This addition is based on a PR and it's still under review, not sure if it will be maintained in the future. In general, raylib tries to avoid callbacks usage mechanisms.

As prior commit, but complete fix for XBox controller and trigger
buttons too.
