This reverts commit 0cf70a6e.

NEOgo and NEOpy diverged regarding the NEO zurl format. Due to NEOgo
changes in NEOgo 0cf70a6e was necessary.
However in neoppod!18 and
neoppod!21 a common
zurl format for NEOgo and NEOpy was agreed on. Therefore most changes of
0cf70a6e are no
longer necessary. We still need the difference between 'neo' (without
SSL) and 'neos' (with SSL), but we'll re-introduce this in the next
commit.

This revert keeps the changes made in 6fa1d9ae as this is still
needed.
