[BUGFIX] InlineSettings broken if extJs not loaded

The pagerenderer can add javascript inline settings to the output.
This does not work if extJs is not loaded, because of missing
initialization of js object TYPO3.
This patch makes sure that TYPO3 object is iniitalized correctly,
if extJs is not loaded.
