Dark green abstract per Sangligli

1.0: This is my first theme! I tried to make it as clean as possible, while using a dark green theming.

1.1: After almost a year, here is an update! In this version I've changed some of the details to keep with the overall theme. For exemple: the bookmark's star and the vertical separator in the bookmark's bar are now green. Also, I removed/made darker some of the grey lines that separate the differents elements of the UI (ex: pop-ups, toolbar, sidebar, ...). Enjoy!
