Version 79.5

This version fixes an important 'double-arrow' bug that can occur, when an Ndyan shoots their arrow, as well as some other minor tweaks. (The importance of this being fixed, being heavily based upon the fact that Ma' Belle is supposed to be able of taking 2 arrows, before dying, rather than 1)

On top of that, this adds the first draft of the "Showdown" -mode; More detailed info coming in the near future; For now it's only available as a test-level. It does not 'work', per se. and is only there as a sneak-preview of things to come.
