Replace some text with unicode in print.apa_results_table()

[mariusbarth]

For complex models with higher-order interactions, the output from apa_print() sometimes becomes rather unwieldy. I am wondering if it would be a good idea to print() interaction terms after replacing "$\times$" with the corresponding unicode character. This is what something like that would look like:

$table
A data.frame with 7 labelled columns:

I think this is a design decision. We usually print exactly what is "in" the object, and I think for expert users this might be the best choice. On the other hand, getting beautiful output in the console is also something to like.
