Making ordering of relevances more explicit

Currently the suggestions are not always totally ordered (e.g. there are
some with default of 0), even though Eclipse then fall back to comparing
strings, it would be much better to have an explicit ordering.

This now:
- make creating a commented compatibility filter "more recommended"
- make removing an unused filter "more recommended"
- make configure the problem category "less recommended"
