Version 1.3 released! Hurray!

A late xmas present for all of you!

Changelog:

• Added game over screens to the RPG and danmaku stages.
• Bernkastel will now skip the introduction dialogues you've already read.
• Fixes a bug that caused powerups and points to not appear most of the time in the danmaku stage.
• You now lose all power upon death in the danmaku stage.
• Added a cool shader to the danmaku stage's background...
• Added a custom bootsplash.
• Updated Godot to beta 1. (EDIT: Godot 3 stable is out, you should probably replace the exe with a copy of it)
