openfng - fix maps

[fstd]

openfng5 needs hostile shrines near the aligned ones near both bases because currently there is no point in going there
openfng4 encourages noobs to hook the ceiling above their aligned shrines and stay there until they get frozen and fall in, causing a unaligned sacrifice
openfng3 is shitty

For the record, openfng5_Beat meanwhile has made it into the repository.

Also Broken/Dizern contributed Epic_Island, Mountain_Shadow and Sun_God, all of which are pretty nice but rarely seen in the wild
