Better distinguishable icons for "untracked" and "added" states

The new icons in SmartGit 26 for "untracked" and "added" states are very similar in color and shape, which makes it hard to distinguish between those states. This is especially an issue in the working tree view, where both icons are mixed.

It would be better if the untracked icon had a different color than green (it previously was blue in SmartGit 25), since this would help to see the state at once without paying attention to the exact shade of green or the additional white pixels between the star and plus icon.
