======
1.7.0:
- [bug] Fix resize (drag and drop) in dynamic sections
- Replace element selection indicator from border to outline
  This makes element contents not move when selected.
- Allow deselection of elements
  Clicking anywhere (but the side panels) will deselect elements. This makes
  it easier to get an impression of how it will look like.
- Add 'line-height' property to all elements which have a font
- Add 'rows' property to text areas
- Change text property input to textarea
  This allows to properly enter longer default texts in text areas. (This is
  also active for text-field elements, where it makes little sense but makes
  it technically simpler to not differentiate).
- Fix lables on text fields
  Now correctly uses a proper label instead of a placeholder.
- Change text field appearance depending on label existence
  When the label text is empty the field will be rendered a lot smaller (and
  without any label obviously)
- Change font-size property to number field
- Improve radio-button-group styling
  Add 10px margin between label and options.
- Fix likert elements sizing
  This should make the selected background color cover the whole element instead
  of just the upper 100 pixels.
- Improve bold text style to be less bold and have letter spacing
- Add read-only property to all input elements and likert
- Allow changing the line-coloring color for likert elements
  (not to be mistaken for background color)
- Add 'underlinable' property to text elements
  This is to allow different purpose markers on text. Does NOT work in the
  aspect-player yet.

- Add Input Assistance property to input elements
  This can be activated by selecting one of the presets, which are mutually
  exclusive for now.
- Add "clearable" property to text field element
  When set, a button at the end of the field appears which allows deleting the
  field's content.
- Add "position" property to "always-visible" pages
- [bug] Fix option elements saving value index instead of actual option string
  This allows duplicate (or empty) options.
- Fix TextEditor indent setting to persist when re-opening text element
- Improve TextEditor margin logic
  Default margin of paragraphs is 0px. It can now read existing margin
  settings.
