Update to v076 release.

byuu says:

Most notable in this release is that sound support has been added to my
own Super Game Boy emulation. The GUI toolkit, phoenix, has also
received a complete rewrite; with the most visible change there being
that windows are now resizable.

Changelog (since v075):
* added sound emulation to Game Boy core
* fixed Super Game Boy save state
* support added HexEdit widget to Windows and Qt targets; debugger can
  now be compiled on all platforms
* entering fullscreen now auto-hides mouse; and mouse capture is toggled
  otherwise by F12 key
* fullscreen command and geometry caching works much better on GTK+ and
  Qt targets
* phoenix rewritten from scratch; now supports resizable layout
  containers
* phoenix/Windows no longer relies on buggy SetParent API to reparent
  widgets
