OzBsidian colour scheme for Oracle SQL Developer

This is a spinoff of Obsidian colour scheme for Oracle SQL Developer. It is based on Obsidian Eclipse colour scheme by Morinar.

A few days ago I installed Oracle Linux in an Oracle VirtualBox VM. Once it was installed I found that eth0 interface wasn’t starting upon boot. That was unusual.
