[TYPO3-mvc] Extbase and Fluid as a service/hook

[Stefan Frömken]

Hello Extbase-Team,

I just have found a hook to add some selectboxes at the top of each 
table listing in Web->List.
Now comes the step to decide if I style this little part old-school with 
mixed HTML and PHP or with help of Fluid and some PHP-Arrays. I prefer 
to use Fluid, but how to start this without registerPlugin and/or 
registerModule?
