Failure to load an asset file should resut in some form of error message

[fNek]

Steps to reproduce:

1. Copy the code from examples/2d/sprites.rs into a new bevy project
2. Intentionally save the bevy logo, which this example depends upon, under a different file name
3. Forget to change the path in the code you copied
4. Wonder why nothing is shown in the window

I believe there should be an error message printed to stderr or something, since it might easily happen under circumstances where it's less obvious what happened.

Agreed. We currently swallow these error messages and that certainly isn't ideal 😄

I think this can be closed now. We get panics, I think, for failed asset loads now, and in master we actually don't get the panics for hot reload failures, we get nice warnings.

Edit: Even better looks like we get warnings for failed assets after this: #1286.

Makes sense to me!
