// Hotkey conversion routines!
/*
  Wonderful MS - different definitions for everything!

  Used by Windows to Register a Hotkey and also the WM_HOTKEY message
    MOD_ALT             0x01
    MOD_CONTROL         0x02
    MOD_SHIFT           0x04

  Used by CHotKeyCtrl to Get/Set the Hotkey in the control
    HOTKEYF_SHIFT       0x01 
    HOTKEYF_CONTROL     0x02
    HOTKEYF_ALT         0x04
    HOTKEYF_EXT         0x08

  Our internal versions as Windows is different to Linux/Mac
    PWS_HOTKEYF_ALT     0x01
    PWS_HOTKEYF_CONTROL 0x02
    PWS_HOTKEYF_SHIFT   0x04
    PWS_HOTKEYF_EXT     0x08
