Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
This fixes a problem where objects that leave the scene were not being removed from thee scene. Projectiles and enemies now get removed when they leave the scene. There should no longer be a segfault when you destroy the final boss.
