Update to 1.51.78:

Changes for version 78

      * Fixed an issue where, after failing to load a ROM, the
      emulator would be paused forever.
      * Added a toggle to joypad configuration to allow or disallow
      direct use of modifier keys.
      * Changed the option to disable screensaver so that it uses
      XResetScreenSaver and xdg-screensaver due to XTestFakeKeyEvent
      being removed in the latest X.org release.

Changes for version 77

      * Added pt_BR translation. [Tiberio Vitor]
      * Fixed a bug where the sound driver would switch from SDL
      in the Preferences dialog if one of OSS or PortAudio was not
      installed.
