Messages for incorrect usages of Stats, Step(s), etc.

[rljacobson]

This is a feature request, not a reviewer critique.

I really like the Int::noShowSteps message. It even tells me how to fix the problem. Perhaps it would be more clear to say explicitly what "this function" is—obviously it's not the Int function. Still, it's a really nice touch.

I found it really easy to accidentally use Steps, Stats, etc., incorrectly because of my fat fingers. It would be nice to have more messages for incorrect usages like Stats[Int[x], x] or Steps[Int[x], x]. This one is curious:

In[8]:= Steps[Int[x, RubiPrintInformation->False]]

Out[8]= Steps[Int[x,RubiPrintInformation->False],4096]

Good catch! I've turned this into a Rubi issue and I believe both things can be fixed without much work.

I already fixed this.
