HD images, full controller support on selection screens

Dear friends,

By far, the biggest news in this update is the fact that we replaced about 80% of the images in the game, using newer ones with bigger resolution. Because of that, the game now looks much better in HD and Full HD resolutions, especially the bosses and the opening / ending sequences.

It's definitely been a huge amount of work in the last month and a half, but I guess it was worth it. We hope you'll enjoy it.

We also added full controller support on the main menu, jukebox, language selection and difficulty selection.

And last but not least, we corrected some nasty little bugs that were pretty hard to find. ;)
