New template-based-function: remove the uneeded items on a QList.

This function is for non-duplication of code for different QLists, since I
now have Texts and Lines, I needed to make the code in a way that it
worked without dupplication.

It's a pretty standard use of templates, I think that even the C guys will
not be offended by it. :)
