tools: Improve diffability/maintainability

There's no purpose to squish multiple tools into a single line (and
spread those out over multiple lines). It might look 'nice' in certain
conditions, but it's annoying to maintain.

For example, but not limited to:
* adding/removing tools, causes hard to read diffs
* Duplicates are harder to spot
* Sorting can not be (easily?) automated

With this proposed change, the above annoyances go away. Inserting a new
tool can be done with a single line-change-diff, sorting can be done by
any editor (in vi, select, :sort for example) and dupes are much easier
to spot.
