Feature suggestion: Dark Nimbus L&F

[ghaffarian]

First of all, thank you for this great theme! I always wanted a beautiful dark theme for Netbeans, just like the Darcula theme of IntelliJ-IDEA.

I want to suggest a feature: adding a dark variant of Nimbus L&F to the available look & feels. There currently is a plugin named "Dark Nimbus", and I've attached a screenshot of Darcula theme with Dark Nimbus L&F:

As you can see it has its pros and cons. The main drawbacks of dark Nimbus L&F is:

1. The blueish background color of containers, like the project tree (It's designed to match the Norway Today editor theme).

2. Maybe a darker grey color will look better.

   If the above mentioned drawbacks of the dark Nimbus L&F were to be fixed, IMO it would be a much better option to be combined with the Darcula editor theme, compared to the current Darcula L&F. Unfortunately, the orginal "Dark Nimbus" plugin doesn't seem to be active anymore and I was unable to find any contact info.
