Fix some vertical alignment issues, Safari style issues, select and checkbox now uses the primary color

[vincentfretin]

• Remove unused rules
• Set border-radius 0 on input to fix issue on Safari where input id appeared rounded and fix the color picker to be rectangle instead of ovale on Safari
• Use custom checkbox style so it appears the same on Chrome, Firefox, Safari with the correct primary color
• Specify a .select__option--is-selected rule to use the correct primary color in camera select
• Fix vertical alignment issues with entityPrint and icons rendered in scene graph and sidebar header, fix search input to make the scene graph horizontal scroll disappear
• Increase font-weight for .propertyRowDefined to be more visible
