Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
New InitStage system, Screen & Screen.Drawable, separate testing and guiDemo binaries. This (and the previous) commit are the result of several quite significant changes to mde. All the unittests run, but it hasn't had a huge amount of testing so don't be surprised if bugs show up.
