conflict-list sorting

[skyper]

please sort relations in conflict-list by name and not by id.

for nodes it would be nice to have them sorted by position and not by id.
for way I do not know yet, but I'd prefere name or position in favour of id.

Thanks skyper

Grouping would be another enhancement:

1. nodes with only changes in tags, position and state only without parent way
2. ways with only changes in tags
3. nodes + their way without membership conflict in each group, e.g.:
   1. nodes with changes in state with parent way
   2. their parent
4. the rest where conflicts on ways are before their parent relations conflicts in each group
