Subject: [PATCH] Made water oil wells require the Refrigeration tech (#4889)

* Made water oil wells require the Refrigeration tech

Oil wells can now only be created on water with the refrigeration
technology.

This is not the ideal solution: it would be preferable to support
multiple improvements for a single resource, to add offshore platforms
as a separate improvement for coastal oil that requires refrigeration
and to disable building oil wells on coast. Allowing multiple
improvements for a resource would however be a much more significant
refactor.

* Added back "terrainsCanBeBuiltOn": ["Coast"]
