Soo many bugs fixed!

So, in a previous devlog I listed a bunch of bugs. Of these I have fixed almost everyone.

Note however that number 8 is "fixed" but that the behavior might not be what one suspects. I will try to fix that soon - what I mean is that now the zombies most likely notices the player but they might continue doing what they are doing for a while after that. The solution is probably to add a guard or something to almost all tasks OR refactor the BT to use dynamicguardselector - I just had a hard time, this time around, to wrap my brain around how to use it. 

Anyways, please enjoy.

1.  Lights on walls - walls don't stop lights, basically
2. Walk cycle has one extra frame
3. Rate of Fire on shotgun is too fast - sometimes?
4. Hacking sequence needs to be randomized and levelized
5. Pause dialogs need button legend for currently available controllers
6. Typing label / crawl is shit. I want a crawl in that dialog between levels
7. After crawl is done, start level instead of waiting in paused state
8. Zombies do not notice anything when player enters their vicinity sensor
9. Changing levels more than once completely screws up enemies etc, they are outside the map
10. Autoreload - pushing reload is not viable when out of ammo
11. Reload bug - sometimes it reloads more than mag capacity, I am guessing its an error of a bad if-statement
12. Game crashed after five levels, could be a problem with that particular map file

Bugs that weren't fixed: 

1. Better shadows - not really a bug, mate, more like wishful thinking
2. Scaling bug on sprites
