Alternative Icons for "Run selected" and "Run from code editor"

[Lübbe Onken]

The current symbols used for the commands "Run selected" and "Run from editor" look like "fast forward" and "skip to end" to me. Therefore I have created two alternative icons which I include here as .png and attach as .ico, since my icon editor doesn't preseverve transparency when saving as .png

Run selected tests

Run test from editor
