This uses the C fgets() over the weird readLine implementation I found.
It speeds up the rev-parsing significantly: we went from ~4.5 seconds
on the git.git repo to ~0.95 seconds. And that's with the secret new date
parsing!
This adds a new class, PBEasyPipe, which can do most of the pipe handling
in an easy way.
We use this to call `git rev-parse --git-dir` to find our current git
repository. This means that we can now call GitX within a subdirectory :)
This makes the initial startup much faster. Commits get loaded in a separate
thread, and are displayed every 1000 commits.
There is a bug in here that makes fails a click while it is loading the commit
list. Not sure how to fix this, perhaps send the arrayController?
