Battle system finished

Battle system is now fully functional. There is a check if you carry
any weapons and if you do, it presents them in the combat (you can
always select to fight with fists).

Combat system also controls if you have enough bullets or if your knife
or baseball bat is functional (they get broken after few dozen uses).

Now there is possibility to get infected in the combat and die.
Unfortunately I will not build multiple enemies into the combat (I’m
glad I managed to do one-on-one combat). But I might add several
battles in one location.

Speaking of locations - I will now start building some kind of story
and new locations. I believe the scaffolding has been built and there
is probably no more features to be added, probably lots of bug fixes.

Note: when you find yourself after the combat on March Street, the game
will probably fail because there are no other locations to go to, same
goes for other streets leading from Curling Street Junction (location
Junction).
