Add ShortcutMapper MultiLingual ability

Browse Source 
When application is first loaded, it scans through the VK mappings on the active keyboard, and for the keyboard-specific keys (focused on the VK_OEM_# and similar keys), it will read what Windows says is the actual character associated with that virtual key code, and will populate a mapping for display purposes; when Notepad++ is showing the shortcut keys in menus or in the Shortcut Mapper, it will display the keyboard-specific character rather than the default en-US character.

(Debugged locally using Windows' `osk.exe` virtual keyboard app, and users with alternate physical keyboards have verified it for me as well, including the original requester.)
