adds Thumbs.db to the ignored list
Why is this in VisualStudio.gitignore at all (which, as mentioned in #542, should be in Global)? It's already in Windows.gitignore, along with ehthumbs.db (which I've never actually seen but could theoretically be a problem for developers using Git on Windows XP Media Center Edition (all zero of them)).
Am I imagining things, or is the commit (bbabac2) and pull request message inaccurate? Thumbs.db is already covered; you're adding support for thumbs.db (lowercase).
Thumbs.db is ignored in both Windows.ignore and VisualStudio.ignore so I'll close this.
