openttd: change to application bundle with open content packs

- Builds an application bundle instead of the CLI launcher
- Downloads OpenGFX, OpenMSX and OpenSFX and installs them in the bundle
- Updated the caveats to reflect the Open* packs and point you to
  instructions to install the original assets
