Updated README.md
Added a Room Exit Editor UI mockup.
Enabled the Save button to the Environment Lighting Editor. It dumps out the EnvR chunk (and all the others as empty files!)
Added the FSHelpers class to add in some helpers for writing Big-Endian values.
Added FSHelpers::WriteArray(...) to make writing byte arrays easy.
Added WriteData to the IChunkType interface.
Added ShoreFadeColor to the Pale section.
Fixed a pretty serious issue with changes to the index fields overwriting values we needed with the default form value. Oops!
Fixed a read error in Pale's Chunk type that prevented it from reading the correct Ocean/Shore fade colors.
Fixed BitConverter not returning the correct length bytes (see FSHelper::ToBytes)
Added couple new fields to the UI.
