Lock testing in edit mode. Significant bugs fixed: editor, lockfile reader, and validity checker were not in accordance on what is allowed as the root of a spring. SDL UI was redrawing the screen on every mouse movement. curses UI wasn't refreshing properly on async flag. stale notes weren't getting refreshed. retired display got stuck on changing codename. you couldn't move into the bolthole with keyboard commands. 0.2: First public release
