[BUGFIX] Introduce failsafe view in install tool

The installer does not work, if doc comment reflection
is broken, so we need to make the first install step
more robust by using inject methods and introducing
a failsafe view which does simple php templating
in case critical errors (like doc comments disabled)
occur.
