This was breaking old saves

Also adds a way to exclude one form from receiving the
allForms sizes for a character.

This also fixes the select boxes going way out of bounds

Previously, entities always appeared in the middle of the screen
with an unlocked y-axis. Now, they will appear on the ground
if snapping is enabled and the ground is in sight.

This means you should be able to type the singular
or the plural form for most units now.

This also adds an option to enable editing *any* attribute

Custom attributes will take string input and then decide if it is an acceptable
type of unit.

This also consolidates some stuff related to updating CSS properties
into a single function.

This reverts commit 8b1f7ef612.

This reverts commit af3991d5f2.

Also allow views without a form to show up on
every form.

Also fixes a bug with default form sizes

Also corrects a bug with the rendering of flipped entities

Also fix a bug where allForms-tagged sizes would have their
default flag ignored

This reduces duplication for characters that have many equally-sized macro sizes for
their various forms.

This sets the unit that the attribute will be shown with. It
uses the same mechanism that's used to remember what units
you had selected.

The ground now defaults to very-low, not bottom.
Zoom-on-add defaults to off.

This allows for multiple filters to be applied simultaneously. This commit
also moves some misc stuff, like the help and donate buttons, into a new
info menu. This also fixes touches outside of a popout menu not causing
the menu to close.

Also update the scripts to support tagging entities
with masses and volumes.
