Subject: [PATCH] support more keys in textarea (#1820)

Added:
* C-m for newline (not sure if this is actually treated differently to
Enter, but tui-textarea handles it and it doesn't hurt)
* C-d to delete one char forwards (same as Del)
* A-bksp to delete backwards one word
* A-arrows to navigate by word
