Avoid unnecessary horizontal scrollbars

Fix long key values rendering with horizontal scrollbar; Fix keys folder with checkbox in one line and key name in another line.

I'm curious, why do you think showing ... is better than having a horizontal scroll bar for very long keys?

Hello Erik, you are right. In the case of long key names, the scrollbar is better. I put a title="..." to show the full key name when mouse over and fixed the scrollbar behavior for newer browsers.

Can you please check this in Firefox as well. I'm not sure why but the padding on the right frame is gone in Firefox:

I've tested in Firefox for Windows and the padding was not missing. Instead of padding inside the iframe, I changed to margin outside the iframe. Can you please test in your environment?

Looks good, thanks!
