New this week:

1. Polished the melee weapon, now its an animated punch.
2. Added new weapons:
   1. Mine that freezes enemies. You can upgrade its size, freeze time and rate of fire.
   2. Defence drone that surrounds the explorer. You can upgrade its power and speed.
   3. Grenade that explodes. You can upgrade its size, power and rate of fire.
3. Fixed a bug that made the tooltips not show on the exploration screen.
4. Fixed the position of the camera when you open the planet map.
5. Changed a few terrain sprites to experiment a bit more, I'm still trying to find the right look and feel for them.
