Viewhelpers for strtolower/strtoupper
I would like to see 2 viewhelpers for strtolower() and strtoupper().
At the first this maybe sounds silly because this can be solved with CSS but this is not entirly true. There are languages (e.g. greek) where doing a simple "text-transform:uppercase" will be stupid because this can change the meaning of the text. The reason is because CSS is stupid and doesn't take the locale into account but PHP does.
