Update to v092r06 release.

byuu says:

Changelog:
- added support for ruby shader folders (place in "Video Shaders/")
- higan now also looks in your shared folder for configuration files and
  system media folders
- added CFBundleExecutable key to OS X Info.plist

Shared folder locations:
- Windows XP: C:\Documents and Settings\All Users\Application Data\higan
- Windows 7: C:\ProgramData\higan
- OS X: /Library/Application Support/higan
- Linux: /etc/higan

Evaluation order:
- look for item in binary folder: if found, use this folder
- look for item in user folder: if found, use this folder
- look for item in shared folder: if found, use this folder
- create item in user folder

For people repackaging higan for other distros: you should chmod 777
/etc/higan. Failure to do so could result in higan breaking. No, I will
not copy the files from the shared path to the user path.
