Themes: Show an error message to logged-in users if a template file isn't loaded.

Browse Source 
On the off-chance the active theme folder is renamed or deleted, a "white screen 
of death" was displayed to the user. Instead, the user is shown a useful error
screen displaying any errors the theme has (e.g. if the theme can't be found).

Props MikeHansenMe, SergeyBiryukov.
See #21931.
