Renderable property info walkthrough/cleanup (#3226)

A passover of all the Parameters descriptions and PropertyInfo descriptions of the renderables in the code base to make then more consistently and concisely formatted. Also fixed some small issues and added or updated descriptions.

* Start rephrasing propertyinfos for more consistency

* Update eclipse cone propertyinfos

* Update `RenderableFov` property infos and group colors in UI

* `RenderableGalaxy` and `RenderableGlobe`

* Update more descriptions

* Moore descriptions

* Update docs for `RenderableShadowCylinder` and add properties

* `RenderableSkyTarget`, and spheres (`ImageOnline` and `ImageLocal`)

* `RnederableSphericalGrid`, and update line width info of other types, for consistency

* `RenderableStars` and `RenderableTimeVaryingSphere`

* Update more propertyinfos

* Fix inconsistent mentioning of true/false

* change some phrasings for increased consistency

* Update Renderbin description to include Sticker bin and remove extra property

* Rename `OutlineWeight` -> `OutlineWidth`

* Extend description about enable depth test for models

* Clarify what relative values mean for `RenderableNodeArrow`

* Elaborate on `RenderableLabel` size property
