Fixes #271

The new algorithm mangles the request string as before,
but then looks for the first valid number instead of
a number in fixed places. This hopefully works for
all firmwares.

To avoid future regressions, a list of sample strings was
started. Feel free to add more samples in.

While neither PCB milling nor comments in parentheses are
part of the innermost core or RepRap printing, they happen
and should be handled gracefully.

Do not echo messages from printer twice when in loud mode

Add debug option to menu

As this is now part of the standard interface, it's pointless
to list it as possible extension code.

In a source code repository, all sources should be visible,
including those meant to be hidden at runtime.

In verbose mode (self.p.loud = True), the code actually sending
the G-code line prints this, too, so this was a duplicate.

Making these visible should help users to find out what's going
on on unexpected printer behaviour.

No new functionality.
