Only Fen has a tag, and most characters lack species,
so it'll be a while until this covers everyone.

Entities can have now a default view other
than the first one provided for them.

Units that didn't match the internal base unit
were showing up wrongly.

This also fixes a bug that caused the initial value for

the unit used internally.

This way, small values don't just become 0, and large values don't
have tons and tons of digits

The fields displayed weren't actually changing when changing views.
This also fixes a bug that was attaching tons of
event listeners for nsfw highlighting to the view list

They'll always be 3/10ths as tall as the world is.

This also gets rid of the groups, which were messing up the layout.

All of the entities are rendered to the canvas. It only renders images, so there are no
names, height bars, etc.
