Optimize stdWrap usage for tslib_content
There are lots of parameters still left in tslib_content that have not been covered by the stdWrap optimization of the content elements.
Some of them already use stdWrap, some of them don't.
Those who do use it, often don't check for stdWrap functions before calling stdWrap.
The attached patch changes this behaviour by optimizing the usage of stdWrap wherever it occured and introducing additional stdWrap functions to parameters who hand't got them before.
