Updated Menus

With the Fertsoft 5.0 release we have done some work on the menus and shortcuts available throughout the system.

New Menu items

- New Window (Ctrl + N) - Opens a new window with the same work screen that you are on
- Close (Ctrl + W) - Closes the current window
- Home (Ctrl + H) - Navigates to the Home screen
- Log out (Ctrl + U) - Logs you out of the system and returns to the Login screen
- "Lock/Unlock scroll wheel" has been renamed to "Show/Hide Toolbar" to more accurately describe what it does
