Animate robot/drone selection via mcmeta

[SquidDev]

This moves the robot/drone selection animation to be done via an .mcmeta file, rather than manually. This also adds some missing enableBlend/disableBlend calls¹, fixing the translucency of the texture.

Due to limitations in the mcmeta format, the "frame time" is defined in ticks, rather than milliseconds. This means the animation plays out slightly faster, at 20fps rather than 17fps. I don't think this is really noticeable (unless doing a side-by-side comparison), but wanted to check we're happy with the change in behaviour.

Footnotes

1. Annoyingly blitting with a custom color enables blending, but doing it normally (like here) doesn't, so we have to do it ourselves. ↩

I suspect no one will seriously care. I doubt the original weird 17fps number was deliberate; it probably just looked good (enough).
