Remove $Id:$ tags

Git doesn't support these, so they show misleading info anyway.

I'm not sure if there is value in leaving them, but git does support these they are just off by default. Changing your gitattributes will make them be populated with a string that would allow you to go to the exact same spot in the repository as someone reporting a problem if they included the string.

http://git-scm.com/docs/gitattributes

When the attribute ident is set for a path, Git replaces $Id$ in the blob object with $Id:, followed by the 40-character hexadecimal blob object name, followed by a dollar sign $ upon checkout. Any byte sequence that begins with $Id: and ends with $ in the worktree file is replaced with $Id$ upon check-in.

That's why they were there in the first place; you could do "strings" on your binary and figure out from that where the repo was at the time the binary was built.

It's been years since I had to do that for a particular debugging session, but it sure was handy when I needed it.
