A bit more about TESFile

[Meridiano]

Move TESFileFlags and TESFileIndex into TESFile scope.
Make fileFlags member REX::TEnumSet.
Add TESFileText for author and description members.

actually, it might be better to keep TESFileFlags and TESFileIndex in the RE scope, otherwise refering to them would look like TESFile::TESFileFlags

The idea was taken from BGSEquipSlot::Flag and other similar cases already present in CLib. I can move TESFileFlags and TESFileIndex back to RE, or I can rename them to Flags (so, TESFile::Flags) and TypedIndex (because just Index is too vague, there's already compileIndex member) (so, TESFile::TypedIndex).

What is more preferred?

I like the first more, but the second is fine too
