Add IsExplicitlyNull to check if a weak object ptr is really null instead of just missing, this is much faster to call than IsStale()
Comment and coding standard fixes for weak object ptr requested on review

Add new GetAuthoredName functions to UField and UEnum that expose this via virtuals instead of doing it in data table utils
If PPF_ExternalEditor is passed to export text, it uses the authored names and also turns off delta serialization for containers
Change CustomFindProperty to not be editor only and add CheckAuthoredName to enum name lookup, this allows importing data tables using user structs at runtime for hot fixing
Deprecate UsePrettyProperty/EnumNames for data table export, the comments were wrong before and that behavior is now always enabled
Changed several functions with "DisplayName" to use authored or friendly name instead, as DisplayName should always refer to the DisplayName MetaData and is usually translated

Getrandom syscall was introduced in version Linux kernel v3.17.
Can be disabled with -norandomguids command line option.
