The "look at me still talking when there's mapping to do" update.
UI: Make display more responsive during long busy periods. Use Hildon banners
if available, or temporary statusbar messages for non-Hildon. Some message
wording changes.
Bugfix: Prevent some segfaults when tapping screen during a redraw by putting
a grabby banner in the way.
Etc: Update credits.
