v1.3.0

Added

• Added right sidebar with station info and avatar image, wherever
  the image is available
• Added a new menu item to check for newer versions and start a
  selfupdate, if the user approves it. There is a way to see the
  latest changes before update.
• Added a play button at the right sidebar which is enabled as soon
  as the user selects a radio station. By clicking it the radio will
  be loaded at the default player. The double click on the radio
  list was disabled.

Fixed

• Now the radio list is cleared if the search criteria change and
  no radio stations are found
• Now the list is not cleared if the "Discover More" button is
  clicked and no more stations were found
• Fixed a possible crash on window closing

Changed

• Added a new message in case the "Discover More" button is clicked
  and no more stations were found
• Dropped oo.library network support for libcurl. That's why the
  executable size is increased so much
• Now oo.library and AmiSSL are not required
• Fixed the version string to include the application name
• On every request of radio stations, a list of 100 stations are
  returned and listed
