System Information
Operating system: Windows 10
Graphics card: GTX1080Ti

Blender Version
Broken: 2.8, 2.7

Worked: never

Short description of error
Group Node Node Editor theme property is missing alpha channel, resulting in inability to set transparency of node group background in node editor. This in turn makes it much more difficult to work with node groups, as transparent background makes the node group appear visually much more cluttered, being very difficult to distinguish between contents of node group and contents behind transparent background. There are no other theme properties inside Node Editor theme section which affect this transparency amount either. What this effectively means is that at this point, node group background transparency is hardcoded.

Exact steps for others to reproduce the error
1, Open node editor, create a few nodes and make a node group of them
2, Enter the node group
3, Open user preferences, go to Themes>Node editor section
4, Select Group Node color swatch, and modify the color
5, Notice that the color of node group background changes but transparency does not
6, Notice there is no way to change the transparency of node group background

Result: Node group background transparency can not be changed

Expected: Node group background transparency can be changed
