suggestion: remove texture dialog

[kfarr]

Texture modal dialog is the cause of many issues on github:
#429
#471
#494
#508
#621

it also appears to re-download textures when i look at network activity, effectively doubling download bytes.

Would it make sense to remove this feature?

If the direction that @dmarcos want this repo to take is to stay an inspector and not add any new features to be more an editor, it would make sense to drop this feature indeed, and also remove the aframe-watcher button #679
We can implement a better editor in a fork, I started one in https://github.com/c-frame/aframe-editor to add drag an drop, but no specific roadmap for now.

The only open issues remaining are:

• Add a "remove" button on each texture in texture modal #429
• Add video texture src #599

otherwise the texture modal is working properly.

When you select a new texture, it indeed does the query twice, once to create the asset in a-assets and another one to create an image to render in the modal, but with "Disable cache" unchecked, it says (disk cache) so that's not really an issue as far as I can tell.
