RVAL2CBOOL lax type check

Desktop Ruby-Gnome 2

So we now use RVAL2CBOOL for rg2 library calls awaiting a gboolean
parameter. Though, RVAL2CBOOL is RTEST and RTEST is kinda lax: it
accepts barely any ruby value. So basically you can pass nil, a
string, or a widget and these will all be false (except nil of
course).

What if we added a check in the RVAL2CBOOL macro, to rb_warn on
anything else than Qtrue and Qfalse?

No,no. The values except false/nil becomes true in Ruby.
It’s a correct behaviour. So we don’t need to warn such things.
