[TASK] Removing unused argument "bullet"

The argument bullet designed to insert html before each item, but this is a rare use case especially because there are alternatives fx by css or manual rendering.

Since the functionality for this argument is not yet implemented we will remove the argument.

Who needs something like that should use the manual rendering instead.

[TASK] Make "b" argument on math.minimum and .maximum optional

When "a" is an array, max() and min() will work with just the array as argument. The ViewHelper, however, required a "b" argument which could never be NULL and thus prevented using only the "a" argument.
