Backspace not supported in csysdig on tmux

[charles-dyfis-net]

Observed with TERM=screen-256color. ^H does work.

Setting a breakpoint in curses_table::handle_input shows that when using the backspace key, ch has a value of 127; when using ^H, it is 263.

Even if I don't see the issue in tmux on my ubuntu 14, I tried to address the issue with this commit cb9b66d.

can you please try to build from the 'backspace' branch and tell me if it works?

The backspace branch resolves this issue.
