Suggestions: a few additions to improve app in a good way

[MadRatSRP]

• Dark theme

• Share button

• Instead of wasting time on selecting and copying, it would be cool if we could have additional way to do it:

  a)Copy button with icon, each for Groovy input and Kotlin output (could be placed right to the title

  b)Left to the line numbering column copy button for every line in script, both in input and output (by default invisible, but if you'll hover your cursor to this position it becomes visible)
