Still need to make the divisions more reasonable for larger/smaller values

By default, the world was set to be 1.1 times as tall as the max height
(or the mean). Now, it can be set to an arbitrary factor.

attribution-less characters

Automatic fitting will still move stuff around horizontally.

Having every single property affected by the css transition
meant that switching sources waited for the transition to
complete, and also required for the grabbed class (which
disabled transitions entirely while moving entities). Now,
only height and max-height are affected by the transitions.

Attribution is provided for groups of files that share a common prefix.
Each group can have one or more authors. Each file has one source.
This information is displayed when an entity is selected.

Includes a demo scene, some of the military-themed macros, and then selections
of entities of varying sizes

Mostly just avoiding things like the position of the entity holder over and over.
I should probably switch it so that it just reads, then writes. TODO!

Each entity now has an info object, a views list, and a sizes list.
This will allow for more complex bio/description text
