The overloaded member signal just hit us, to use it is a pain
but the resuting code is faster and less error prone, so it's
still a good thing to do.

C++2003 didn't had variadic templates so different number of
arguments must have been already implemented in the templates
and since it's impossible to get the amount ot different methods
that paople write, a variadic template was neede.

now we can connect signal / slots with 6+ arguments.

First commit of modernizarion of Qt signal connections,
the new signal connection is very userfull because of a few
nice things:

- it's checked at compile time instead of runtime
- it can connect to any function or method, so we don't need
to use slots anymore
- it's way faster because it doesn't need to work with string
comparisson, but it's basically a direct call.

Users are getting confused because we are missing images. Will put back
new fancy version once we get new airframe config plus auto-generate of
images sorted out.
