Mention edbg:fhelp() in wiki, and also mention feature of ModFunList

Sure, you can assume edbg user can read erlang source, but many people don't bother that far.

Please mention edbg:fhelp() in the documentation since it is helpful.

Also, this bit is not mentioned in the documentation:

ModFunList is a list of module names (atoms) or tuples {ModName, FunName}.

it is only mentioned as:

takes one argument containing the list of modules

I think it is hugely userful feature and should be documented.

Good catch!
What do you think about: https://github.com/etnt/edbg/wiki/Tracing#edbgfhelp
Good enough?
