Release of v0.11.0-alpha

I just finished version 0.11.0-alpha. It has some bugs (one of which disallows one to access the import-export functions), but I'll be fixing them ASAP. There's also a massive lack of mutual scrolling, which would be really helpful. Now it even has a Raspberry Pi (or any other SBC as long as it has proper vector (NEON) support) version.

Sorry for the lack of update in a long while, but due to feature creep on my own part, I had to constantly go back to the engine to fix things there. I'll try to keep the feature creep to a minimum next time, and introduce new versions alongside with engine releases.
