[RTTY] EU1SA, AA6YQ profiles in MMTTY

[Phil Duff & Ann Duff]

I've used the "hyper sensitive" profile for the last few years and it 
seems to have always worked very well.  But I've rarely seen this 
profile mentioned until I noticed it in Dave's Excel spreadsheet. 

I've not done any real A-B comparisons of this profile other than 
switching profiles back and forth in one WinWarbler window which isn't 
much of a test so maybe some of the other profiles work as well or 
better.  It just seems to work well for me and from eyeballing the 
tuning window and the the XY tuning indicator the filters seem a bit 
narrower than others.

Some good comparisons of the different profiles performance would be 
most informative.
