* Added support for selecting the dead key trigger characters from a menubar,

offering two choices for acute and diaeresis as well as allowing to switch
  off each dead key completely.
* moved the textview on a line of its own such that the dead key menu and
  the modifier-switching button live together on one line
* added enum dead_key_index and used it at a couple of places instead of
  having to use the magic numbers 1-5
* refactored the actual updating of the fChars buffer from SetKey() into
  _SetChars(), which is now being invoked by SetDeadKeyTrigger(), too
