#add StringUtils contains a bunch of string-related functions which were in FHeaderParser for no real reason.

#summary Verified why @ was disallowed
#extra Also improved the robustness of the path validator and disallowed some extra things that had previously been missed.
#extra Made the way we report invalid characters consistent between FPaths, FName, and FPackageName; they now report all matched invalid characters rather than only the first one.

#summary Implemented a struct customization for FRange and changed these two properties to an FRange, which can be accordingly clamped.
#add Implemented FRangeStructCustomization<> for FFloatRange and FInt32Range.
#add Implemented FFloatRange and FInt32Range mirrors in Object.h, for use by UHT.
#change Changed the Type member of TRangeBound to be an explicitly sized TEnumAsByte instead of a plain enum (so that the mirrored structs for UHT are guaranteed to match).
#change Changed Min and MaxSmoothedFrameRate members in UEngine to use a FFloatRange and added appropriate metadata.
