Created basic layer movement functionality (up, down) (#2108)

* Created basic layer movement functionality (up, down)

* Replaced `and` and `or` with `&&` and `||`, added constructor initialization

* Added move icons. Added that moving layers pushes state to undo stack.

* Cleaned svgs.

* Circle counter doesn't change nubmer when reordered anymore

* Changed move arrow SVGs

* Make down arrow in size with up arrow, fix white colors from #feffff to #fff

* SVGs in unitilypanel for buttons now choose color depending on color theme

* Refactor tool removing code, removed fixme, fixed bug with minimal circleCount

* Set minimal width for buttons
