OSX app builder requires 7z in Windows

[Billiam]

Attempting to build:osx:app in windows fails at the 7 zip command. osx_app.rb is using execute_command(7z) instead of newer #seven_zip_command, and failing.

Adding 7z to the path in windows caused an invalid command line error form 7z. Seems to be related to the redirect-and-pipe, but not sure.

Updating the command to use releasy's 7za.exe did allow the build to process correctly.

[jlnr]

Also happens in windows_wrapped.rb:117 in the current releasy gem.

Thanks for this. I'm afraid I didn't have access to a computer when Billiam submitted this and then forgot about it when I fixed mine again. Sorry for not dealing with this sooner.
