Previously Twig syntax errors inside a component partial would show the incorrect file and line number. This is fixed.
Also simplified the approach so the stack trace is not hidden inside a closure.
Moved hard-coded text in "backend" and "system" to the language files
(English and Dutch). Affected pages: administrator management,
administrator group management, system updates, system settings, email
settings. Also made some strings more generic for general use (like
"Saving...." instead of "Saving administrator account...")
