New font & bgm

Finally replaced the font Microgramma, which requires a license in order to be able to be embedded onto the file, into Goldman, a font from Google Fonts. It wasn't an easy find, nor was it an easy decision to replace. But I can't force everyone to pirate microgramma.otf just so they can experience Stag the way I intended it, so either I get that license or I change my artistic vision and choices. And I chose the latter. Maybe someday, I'll consider buying Microgramma for real.

Fixed the buggy glitchy sequence in the opening level, and an end-card at the final level. Thanks CompanionMonkeGaming for the report and suggestions.

Added music from a certain anime released in the 2006, retouched it so it loops endlessly.

And uh, completed the level build sequence animations on the second level before the last one.

I think that's about it. Nothing new and polished I could show to people as of yet. See you next update.
