Real-time signals support (for kill command)
SignalsPanel_new now fetches SIGRTMIN and SIGRTMAX and generates real- time signals entries at runtime. All signals between SIGRTMIN and SIGRTMAX are written in "SIGRTMIN+n" notation, per discussion in pull request #551. Signed-off-by: Kang-Che Sung <explorer09 @ gmail.com>
