Now there's a Config type, that's extracted from the git config at startup. Note that laziness means that individual config values are only looked up and parsed on demand, and so we get implicit memoization for all of them. So this is not only prettier and more type safe, it optimises several places that didn't have explicit memoization before. As well as getting rid of the ugly explicit memoization code. Not yet done for annex.<remote>.* configuration settings.
