Build Mac added

I added a Mac build compiled on my old linux. I can't test it myself, so if there is any problem with it, please report about it.

I also added some minor corrections to all builds. Normally I would have waited until I had more to upload, but one of them is a tutorial message who was written in French, so I couldn't let it like it was. The tutoriel message for those who missed it:

When no command is selected, pressing the left trigger (or the Page Up button) displays the information obtained on the already scanned or defeated enemies.
