Dolphin Versioning

[Mobmaker]

I agree that it isn't always worth doing, but it's been **five years** without any meaningful change to the "5.0" number. I feel it should at **least** be 5.1, considering I accidentally installed 5.0 plain earlier, and not only did my Wiimote not work, my game wouldn't run, and NetPlay was dysfunuctional. That much a change in performance should at least be put up to 5.1, even if it's not completely stable. At least just do it for the beta/dev channels, even if you're not updating stable release. 5 years of development all being under "5.0" is really, really confusing for new members.
