Fixed the order of the statistical values:
Additionally, the model group uses the statistical values to build its contents dynamically.
- I simplified the code at some points where percentile and std was accessed.
==== Simon did a few things, I merged his old branch into this to keep them:
- I (more or less) made Add- and EditModelGroupModal have the same style
- NEW: I added the hover effect to the header checkboxes and resized and aligned them
