Subject: [PATCH] Add additional readline-like keybindings. (#524)

Adds the following conventional readline-like keybindings:

  - `Ctrl+H`: Delete the previous character.
  - `Ctrl+D`: Delete the next character.

Additionally, remaps the Debug Console command from Ctrl+D to Ctrl+O, which had been first introduced in PR #486.
