[TYPO3-mvc] Invoking fluid outside the automatic call in controllers

[Steffen Ritter]

now to the right list...

Hey list,

for all who probably might need this, I'll provide a function which 
renders a template file with fluid and returns the rendered string.

Me - for example - use this in may Repository. Wondering why:
I extended the "update" function, so that "onUpdate" of every Object I 
can write it's representation to file system.
In my special case im writing an apache vhost config file to the 
filesystem on saving the "vhost" object.

I hope this might be useful to someone. I think this also could work 
from eId oder cli (not tested).

regards

Steffen
