[Idea] PPSSPP Windows Updater

[Ryan86me]

As you all know, the git builds for PPSSPP are updated quite frequently, often adding new features, fixing compatibility, etc. I think that it would be useful to have an optional updater program for Windows (or any other platform, for that matter) that, upon launching, would update PPSSPP to the latest git build. It would save a lot of the hassle involved with downloading the newest build, unzipping it, and transferring the save/ini from the previous version when updating the program. Anyways, that's just my 2 cents ;D.
