* move file diff at the same level as diff-stats
* make diff-view options sticy again
* make diff-stats scroll if to mouch
* rm useless css info
* less: mv diff-stats to own class
* use new css class
* cleanup less file
* diff-counter: margin-right: 15px;
* make CI work
* make numbers colorful
* add sign (-/+) to numbers
