hswaw/signage: reuse compiled shader, better error handling

Shader will now only be recompiled whenever its code changes. This helps
with hangs on node transitions on underpowered devices.

If shader reload failed an error message will now be rendered over an
existing shader.

File load errors are properly handled.
