v.0.1.8-design-alpha: Update script.js

I got still some problems left:
- the string "Trading Stack:" does not change color when going into darkmode.
- When Opening the homepage, I want to jump right into the 'trading stack' field, so I can fill it out.
- after that, I want to go to the ticker field (this has to be a field where I can also enter a string!)
- after that, Entry, TP, SL, Win Probability, and with the next tap, I create a new row.
- When I finished all entries in a row, and I hit enter. This should automatically push the calculate button

Other problems are as follows:
- The values I enter into Entry, TP and SL should be integer values.
- after entering different values and hit the 'calculate' button, all my entries disappear, but nothing else changes. This is wrong.
1. the 'trading stack' incl. the entrie I put in there, should stay there.
2. The whole table of the ticker and so on, should disappear, and
3. a new table (called results, from you the last time) should show up, with the correct answers, as before.
