Inkubak freshened up

To ensure Inkubak continues to be played for years to come, I made a new release with recent techs (latest Ren'Py engine).

I also added new art for the intro, as well as an animated title screen -- while I were at it :)

Plus some miscellaneous fixes: made some parts less grindy, simplified the password sequence to help with web/mobile, and fixed typos and translations.

I hope you like it, and if you do I may be tempted to expand the ending.
