Retrieve the translation string for the given lang key.

In order to achieve the correct caption text, the function tries several translation strings sequentially.
The first language key that is set will win, even if it is to be considered empty.

This message is looked up in the following order:
1. $GLOBALS['TL_LANG']['MSC'][<mm tablename>][<render settings id>][$langKey]
2. $GLOBALS['TL_LANG']['MSC'][<mm tablename>][$langKey]
3. $GLOBALS['TL_LANG']['MSC'][$langKey]

@param string $langKey The language key to retrieve.

@return string
