Title: Adds Git.logBetween(from, to, callback)

I needed to get the log between two refspecs, and that's what `Git.logBetween` allows.

Given a `from` refspec, and a `to` refspec it returns an array of commit hashes, ordered by commit time.

I lifted the parsing of an individual line of the summary log from `logFile`, but only for use in `logBetween`, since that would technically change the resulting hash if used in `logFile`.

If you're happy with this as a start, I can finish that refactoring for `logFile` to use `parseSummaryLogEntry`, and add some tests for `logBetween`
