PostJ Jam update 1.01

This is a first post jam update that contains few major bugfixes, little changes and the code has been revisited on few places as well.

- main fix was done on the timers, that makes the game to behave more as expected. Main issue was that the timers were not reseting and that caused game to end after short while. There are many hidden timers:

• timer for bomb that will appear in a random house - once the bomb is picked up, timer resets now
• separate timer is for when player is holding the bomb - this one is reset once the bomb is dropped 
• and when the bomb is in the ground there is another timer

Those timers are separate on each other in order to follow the theme (Unstable), that means you would expect when the bomb is about to explode, but different timers makes it harder to predict

another features fixes:

• when the bomb is dropped, it can now kill player if standing too close
• new camera system
  • if the building is about to explode, camera will switch to the explosion (so it is more clear to the player what is happening)
  • there are few preparations in code for more stuff with cameras in the future

• removed few unsued and bad UI elements
• some code cleanup for better performace and towards readability of the code

I plan few more updates as I want to practise few more stuff on this project, but there is no real timeframe of delivery.
