[TYPO3-core] RFC: eval API (#1639)

[Michael Stucki]

Hi Ingmar,

Seems we both agree that the old code was too big for having a short look
at ;-)

Well, I must say that it looks very simple and logical to me.

> I chose 'tce' instead of 't3lib/class.t3lib_tceforms.php' as the second

Should be ok.

> The patch should be pretty much non-destructive because it only does
> something when evaluation names starting with "tx_" are called, so it
> doesn't change the way the original evaluations are handled.
> 
> It has been tested and confirmed to be working by Thomas Hempel.

> I would like to commit this patch before RC1 is released on January 24.

I just tested it using the example extension you sent me. I must say it
works very nice.
