Fix undefined behavior bug with errors.
...
janet_vm_return_reg should only be set when janet_continue
is called. Otherwise, a panic may dump it's error message in
the wrong place, resulting in undefined behavior (often showing
the last return value or worse, segfaulting).

Fix some code style, add tuple/type function.
...
We need to be able to detect tuple type from janet code, otherwise
tuples will contain hidden state. The tuple/type function is able
to detect the flags in the tuple so the programmer can access them
if needed.

Disable tail calls in the root scope for better
stacktraces, as the root scope may contain a single call
to a failing function, as in the case of the test suite.

Add Matchtime captures to peg (Equivalent to LPegs lpeg.Cmt).
...
This allows that pattern to call an external function to
check if some text should match or not. This allows for
matching any possible language a computer can recognize.
