LibGUI: Add Ctrl-H to insert mode
In Vim, Ctrl-H is effectively equivalent to backspace in insert mode, as it deletes the previous character. This commit implements method delete_previous_char() to TextEditor. delete_char() already exists in EditingEngine, but it deletes the next character rather than the previous. delete_previous_char() is then called from within VimEditingEngine.
