UI Updates

[miridius]

Updates based on the new wireframes from Hayley plus other misc suggestions/ideas

• [x] Outline is too thick when zoomed out, one solution would be just use a fill and no outline. Problem with that is when several wrong guesses share borders they will just look like a single blob. A compromise could be a thinner outline + lighter fill. Good candidate for something to put in the settings.
• [x] Hide the all the stuff below the input when phone keyboard is open (we can use https://developer.mozilla.org/en-US/docs/Web/API/VisualViewport or https://developer.mozilla.org/en-US/docs/Web/API/Screen/availHeight to detect a resize of the available screen space to detect the keyboard being open)
• [x] Guess buttons/drawer UI update
• [x] Header UI update
• [x] Search UI update
• [x] Update help screen
• [x] #33
• [ ] #34
• [x] Fix extra motion on game start
• [x] Fix search results background not being in front of map on iphone
• [x] Remove already guessed countries from search results list
• [x] After game is over and full map is shown, when selecting a past guess go to only that country instead of that + target (to fix issues with zoom level cap)
