git-url: display github urls on the command line

Sooo sexy seeing people right PHP for the CLI. :)

Here's a minimal solution with a single line in .gitconfig which also works with git's tab completion:

[alias]
    hub-commit-url = "!f() { sha=$(git show --pretty=%H ${1:-HEAD}) ; git remote get-url origin | sed -e 's%[email protected]:%https://github.com/%' -e \"s%.git\\$%/commit/$sha%\" ; }; f"
    hub-file-url = "!f() { sha=$(git rev-parse $1) ; git remote get-url origin | sed -e 's%[email protected]:%https://github.com/%' -e \"s%.git\\$%/blob/$sha/$2%\" ; }; f"
