SVG + asset reorganization (#10)

* Assets reorganization

* forgot 4 pixels in alpha grid oops

* Updated huegradient.png

Reduces file size by only use 1px height instead of 720px while maintaining quality

* we do a little renaming

* new assets mapping

* moon I hate you

* e

* moon is weird

* make it compile

* temp

* part png rendering

* svgs

* fix some positionings and stuff
