Align and distribute: use section instead of tabs and group of buttons instead of comboboxes
- Uses sections instead of tabs (all buttons are always visible)
- Uses groups of toolbuttons instead of comboboxes (all options are always visible)
- Replaces the input box with the position of the reference guide by a pulsing effect on the specific "reference" button (only when the button is checked); the tooltip of the button contains the position of the guide used as a reference
- Restores the left to right and top down order of the actions, as it was in 1.6.
