Data Update - v0.4.0

This is the first update adding features in a long time.

- I've now added one more tab: the Data List Tab. It contains useful information to assess the situation of the epidemic.
- I have also added a new series of actions: the Society actions. They are useful to lower the odds of losing the game because of the situation getting out of control, they can also lower the price of all actions and increase the funds you get.
- Actions' effects are modified to match better with the game itself, giving a more balanced equilibrium to the number of actions you'll need to buy and their effectiveness.
- I have also nerfed down the disease to make it not easier, but to rather give the player more time to deal with it. Hopefully it'll now be somewhat balanced.
- I have reworked the UI to make it much much more pleasant to the eyes and consistent.
- I fixed a bug which allowed isolated people to move... they're not supposed to.
- I have done some other checks and fixes.

I'll now work to make some more smaller updates, adding new features and re-working some of the already present ones.
