[added] [Map] Nest of the Great Egg

[sstair]

Here are my completed and tested maps of the zone Nest of the Great Egg.

The zip file contains the three maps of the three levels of the zone. I have also attached JPEGs of the maps for your viewing pleasure.

The following needs to be inserted into core_mapstyles.xml (this fragment is also in the zip file in core_mapstyles_fragment.xml).
