* Remove all combat ordering code * Use MultiAmount division for damage * Remove damage selection division skipping in tests * Fix Banding, Multi-block, add tests * Fix test * Fix random iteration order, fix new tests * Add more info to choose dialog, make MultiAmountType class instead of enum * Don't prompt for trample damage assignment if none possible * Mark "Assign default damage" on tests, minor other test improvements
