UIFramework v1.2.0

Fixes from an audit of the whole framework, and the logo on the About page.

Added

• The UIFramework logo on the About page. Faint in the bottom right corner, like a watermark, so the window shows
  it is the original framework: brighter under the mouse, its tooltip names the framework's version, a click opens
  its page. It sits under the content, never over a link, in the dark or the light version for the theme.

Fixed

• Help under fields in named rows. A button or switch beside other fields lines up with them again, a button's
  help line goes under the row instead of stretching its column, and every help line keeps a gap to the next field.
• List files are never written over by mistake. A list kept in a file of its own that the game holds open stops
  the save with the reason, instead of counting as damaged and being written from the window. A list that could not
  be read when the window opened shows its defaults, says so behind the red i, and is not written from that
  window.
• Reset page leaves lists in files of their own, transient and read-only settings alone, as Reset all does.
  Both dialogs say what they do: Reset all saves at once and keeps the file as it was as .bak.
• A game setting called darkMode, DarkMode, egg, Egg or rainbow is no longer taken for the window's theme
  and removed from the game's file.
• A condition such as !mode=free always held. The red i now names it, with the way to write it (mode!=free).
• A cooldown that reads a key no setting has is named behind the red i; before, only a line in the log said so
  on every save.
• The version check no longer fails ("Value cannot be null") for a game whose version is no number.
• Add row in a list with a search typed clears the search, so the new row shows.
• Host block: UiHost.Handle clears the window's arguments before it calls the game's handler, so an action the
  handler runs is not taken for a window request. Games get this with their next host-block update.
• The demo game no longer names the framework's repository as its releases, which showed an update pill in every
  demo window after each framework release.
• Docs: Getting-Started's snippet for an existing game declares its three constants and reads its settings; the
  table snippet has the userCooldown its cooldown reads; the DLL goes into lib\<version>\; what ActionName is
  for. Customize: How to play, Log and About sit at the foot of the page list; help and about lines translate.
