Marco Trevisan (Treviño) 5ae5811155 js/main: Throw error if no valid default stylesheet is found
Throw an error using an informative message in case a mode uses a stylesheet
that can't be loaded, instead of crashing later because the theming can't be
properly computed, and thus the minimum size of the actors.
