Version 0.3.0

This release adds support for saving/restoring all* game state displayed on the HUD when reloading the zone:

• Lives
• Coin counter
• Star coins (more accurately than before)
• Score
• Timer

*checkpoint status is currently just reset to "not collected" instead of the actual original state

Player powerup and invincibility status is also saved and restored now.

A softlock was fixed that used to occur upon dying a second time after reloading the zone just after death.
