[FEATURE] Improve API for module using the card layout

The idea of this feature is not to use t3lib_extMgm::addModule (added param) but provide own functions for adding/removing any module to the card layout.

New functions:
 - t3lib_extMgm::addModuleContentCard
 - t3lib_extMgm::removeModuleContentCard
