Autoexpand validator report classes (Error, Warning, Other)

[mkoniecz]

What steps will reproduce the problem?

Currently at least my process for fixing validator issues is like this

0. Download area
1. Run validator
2. Get errors
3. Expand errors/warning group
4. Expand specific error/warning
5. Use right-click and select zoom to
6. Fix problem
7. Upload
8. Go back to 1.

What is the expected result?

What happens instead?

Point 3. (expanding the most severe problem group) happens automatically.

Please provide any additional information below. Attach a screenshot if possible.

I think that vast majority of people fixes more important issues before less important so automatic opening error group will save significantly more time than waste.
