It's time to start using a proper logger so we can control the number of
log messages, also - it helps to have a central configuration point for
the logs, specially since I would like to hook them up to Crashlytics in
the future.
It's not perfect as our implementation of git pull results in an extra
merge commit and doesn't handle conflicts properly, but it is a basic
implementation, so at least we have something.
For now I've mostly tried to follow the same style guide as the flutter
repository, with many options disabled. Eventually, maybe it would make
sense to be far stricter.
