April v0.502

Thank you very much for the feedback you gave us during the past weeks! 

New features:

• The pickup radius of all items is noticeably increased during a dimension switch.
• When April tries to use a portal stone but can't leave the area yet, the demon will tell her why.
• Added v sync options to the graphics page of the menu.

Bug fixes:

• The "Mindfulness" skill that should have regenerated hit points while not in combat did not work most of the time. It has been changed to regenerate hit points at any time.
• When using a PS4 controller on Windows, the d-pad's vertical axis was inverted. No longer, my friends. We got your back
