Improve UX in build artifacts browser
This improves UX in build artifacts browser, and makes it more consistent with repository tree browser we already have.
Before:
After:
It is easier to click on a file/directory entry now, because we don't need to click on a entry's basename (that can be really short, like ..
parent directory). We also show Compressed to
size that indicates how much storage does this entry really consume.
Row for an entry is also highlighted on hover and we do not have Download button (clicking on a file row / file basename is enough to download a file).
