"Dolphin at GitHub" doesn't make much sense IMO. We could also make it say "Source Code" or "Dolphin on GitHub".
I also changed "Dolphin Website" to make it consistent with the Qt version.
According to GameTDB's database, this is not a known title ID. It was likely added by mistake. For those wondering, DVDX doesn't use this or it would be in GameTDB's database because they also keep track of homebrew, and Dolphin doesn't have INIs for homebrew/hacks anyway.
These are mostly some edits to clean up inconsistencies in the Readme.
Rationale for the edits:
Switched places of Wii and Triforce in lists. Triforce emulation is pretty obviously not treated with the same importance as GameCube and Wii emulation is and so I feel it makes sense to have it listed last rather than second.
Made the spacing between slashes consistent. In some locations slashes had spaces and in others they didn't. I chose to add spaces throughout as it makes it a bit easier to read.
Gave Linux and OS X separate lines in the system requirements. If Windows gets its own line it makes sense for Linux and OS X to also have their own lines. This also clears up a potential ambiguity in what 10.9 is referring to.
Unified title capitalization. Some titles used capitals for the whole title and others only used capitals for the first word. I decided to capitalize all the titles.
Removed Vista or higher as higher as a requirement for using D3D. As Vista or higher is already a requirement for running Dolphin on Windows this is completely redundant. Also cleaned up a bit of a typo here.
