Conversion of key files to keynote file format

Both .key and .keynote files are used for presentations made using Keynote app from OS X, however each come from different version of the software. It should be still possible to save newer .key files to older .keynotes, but you will need to tweak the program preferences and set it to KEYNOTE format instead KEY.
