[TYPO3-core] RFC Feature #9373: Integrate string replacement to stdWrap

Very good idea!

There's two things that I don't like much:

1) str_replace/preg_replace is called for _every_ replacement pair.
However, both functions would allow to use arrays as search/replacement
values.

2) I agree with Masi that the flag is weird. My suggestion is to split
up str_replace and preg_replace into two separate properties.

That would be solved if there were two different properties for
str_replace and preg_replace.
