in "tag checker rules list" make it obvious which downloadable rules are already used

[mkoniecz]

What steps will reproduce the problem?

1. F12
2. Validator settings
3. Tag checker rules
4. Attempt to check which ones from left are already used

What is the expected result?
It is possible to do it in easy way.

What happens instead?
It is not indicated which downloadable rules are used, both list are sorted in a different ways. On top of it entries in the left and right list have different heights.

Proposed fix:
Sort both list using the same order.

There is the same problem also for mappaint styles and presets. I think the best would be if there is the same solution for all three. For mappaint styles the proposed solution ("Sort both list using the same order.") will not work, since the manually order is important in the right column (and alphabetic order in the left column is good). My suggestion would be to hide or make the text color grey in the left column, if the entry is already in the right column.
