sam, Monday update, first-letter-navigation added

[Willem van der Walt]

Hi,
I think sam is about now what I had in mind when I started writing it.
Unless people uncover more bugs and or crashes, I think I am about done.
If there is something I have missed, please feel free to say so.
See the README.md file for a detailed explanation of the 
first-letter-navigation.
As always, grab sam from

Kind regards, Willem
