BETA 0.3 new ennemy and help adds

Hello guy's,

This small update adds additional enemy ship. The characteristics of the enemies are changed, it is now evolving over the player, while keeping an edge over the player to have trouble. (I await your feedback to see if it is balanced)

Help available on the home screen or during travel mode. He quickly explains the buttons used and more...

The mining capacity is now activated. (Not for use in the BETA 0.2)

Some minor bugs were also corrected...

See soon guy's !
