[!!!][TASK] Changed TypoScript inclusion method

The global inclusion of TypoScript with the ext_typoscript_setup.txt
file was replaced with a call to t3lib_extMgm::addStaticFile().

The file was moved to Configuration/TypoScript/setup.txt

Warning! Template needs now to be included manually.
[TASK] Only render configured images

If no image was configured for a poll the new TYPO3 version will still
render it. To prevent this an additional check was added an the image
is only rendered if it was configured in the database.
