Version v0.5.0 Alpha

This release introduces the load/save games feature, and wait...

Yes! your savegames are compatible with Thimbleweed Park, it means you can use the savegames from Thimbleweed Park 👍

This feature wouldn't be here today without the help of @atom0s, thanks for all his explanations, he did an amazing work 👏
And a big thank to @Mac1512 who found a last minute big issue with Windows version.
