[TYPO3-RTE] Add a new headline

[Tyler Kraft]

I'm using htmlarea 1.1.3 and maybe I'm missing something really easy... 
but how do I add another level of headline to the drop down?

I want to add a H7, and H8, and then I need them to actually display in 
the FE as h7 and h8...

Any help appreciated.
