Added serial CW keyer commanding menu item

[OH1KH]

    Suddenly noticed that my winkeyer and IC7300 have different order of CW paddle plug's pin order.
    It was ok with IC7300, reverse with winkey.
    Fastest way to fix this is to set/reset winkeyer moderegister bit4
    This could not be done with Cqrlog as it sends only text to winkeyer.

    Added menuitem: NewQSO/File/Send hex bytes to keyer (W or K)

    Item is visible with winkeyer or K3NG keyer and allows non text hex bytes to be sent to serial line.
    Tested with Winkeyer.
I do not have K3NG to test but assume it possible can be useful also with it in some cases.
The serial sending protocol is same with both keyers.

Help files fixed.
