[TYPO3-mvc] Add Fields in Template on the fly and request hash

Hey Christian,

Nope, the request hash can only be generated on the server, and it is
conceptually not possible to generate it on the client.

You can disable the request hash with @dontverifyrequesthash. The
problem is the following: If you have an object A which has a reference
to an object B, then if you disable the request hash checking, the
system can be "tricked" so it takes and modifies an existing object B
from the database instead of creating a new one.

If you only deal with simple values (arrays, strings, ...) and do the
property mapping yourself, then it's not a problem to disable the
request hash for this action.

Greets,
Sebastian
