Hopping through errors

After nearly two months in closed beta, my backup project is nearly ready for public testing.

Few loose ends left to tie and this was one of them. It's a quick way to navigate between the errors in backup log. For larger backups, there might be thousands of entries per run with only a handful of errors, so inspecting these errors by scrolling and looking can get really tedious.

What this change does is it adds an on-hover previous/next arrows to error messages. Clicking on arrows pulls next error to the spot where the cursor is, and so it becomes possible to click-click-click and go through all the errors in a quick fashion.
