Lost Cavern vBeta 0.2

Major Update!

A lot of people told me that sprites were way too small, making the map indistinguishable, so I decided to correct this problem:

- sprites 2 times bigger, making the different sprites of the map way more distinguishable, and the game more pleasant to play

- you can zoom/unzoom the map (with the keys +/-), which can be really useful

- Quests added

- Crafting fixed

- Enemies colored

- Boring bug fix

- secrets added
