Better fix for accelerator menus using "Back" (previously named "BkSp") key

Use the wxWidgets official accelerator key string for WXK_BACK (this is "Back") in menuitems instead of "BkSp"
Also when reading the hotkey config file, avoid to set a hotkey to unassigned when its name is not found in list.
The default value is used.
Unassigned hotkey use <unassigned> as key name (and 0 as key code) in file.

Fix ASCII code used in accelerator menus for BkSp key (Linux only)

On Linux (GTK?) the accelerator key BkSp, when used in menus must be coded as "\t\b" and not "\tBkSp".
However, On Windows, it must be "\tBkSp".
Joys of multi-platform development.
