Update mcwm to 20110308:

2011-02-23

   * If you change focus window mcwm remembers where we last had
     focus. If you start using MODKEY+Tab to move around the window
     list the first Tab will always bring you to where we last had
     focus.

   * Resets per window state of max or vertical max when physical
     screen size changes.

   * Doesn't reset x coordinate when unmaxing vertically.

   * Specifically grab the keycodes we use and keycodes + shift
     modifier. Now works OK with xbindkeys.
