Subject: [PATCH] efl signals - add signal callbacks for minimal signal set on
 loops

this willonly apply to the main loop, but to be able to see these
signals as callbacks, we have to expose them. term/quit/int are
already handled internally where the loop will terminate (efl will
enforce this) AND ... there is a terminate event already on the loop
to deal with this cleanup. other signals really arent applicable IMHO
except usr1/2 and hup.
