1.4.0.5 compatibility, small tweaks

• Fixed Terrasavr not working with 1.4.0.5.
  Would you believe that those two new items are what introduces breaking changes to the save file format?
• Fixed some items having vertical strip icons.
  Results aren't perfect, but it should work for now.
• Split up version selector on Character tab into two lines
  (because there are too many supported versions now)
• Sidebar is now dark-themed.
  Frankly I've no idea why I had it set to light gray before - the tool always had the dark blue background.
• Removed the Flash button from the sidebar
  (now that it's long-dead and all)

As usual, you can see the current version on the starting screen - refresh or force-refresh (Ctrl+Shift+R) the page if it still shows the last one.
