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.
