dkrenn mentioned in #15003 that the general factorial-function should
check if the element has `.factorial` and executes it. Only if not, it
comes up with solution on its own. (I have not checked the current
implementations; its just came in my mind by thinking about it). IE to add
the following to the factorial() call in sage/functions/other.py
{{{
try:
number.factorial()
except AttributeError:
<do the rest>
}}}
