SkinOptions array was used to determine which options are available
for current session. Once we started extracting things from
SkinMinerva class, we found out that lots of things depend on
SkinOptions.
For example MainMenu/PageActionsMenu depend on skinsOptions var.
We could pass $skin object as dependency to a menu builder, but
this would cause a circural dependency (Skin depends on menu builder,
menu builder depends on skin) which is an anti-pattern.
In order to avoid such situations lets prepare first, and extract
the SkinOptions to a separate class, register it as a service
so different parts of Skin Minerva can freely use a single instance
of SkinOptions object.
