Segfault-award

This is the "Hamlib Segfault Honor Roll". hi.

The distinctive HSHR is granted to people who were able to make Hamlib 
issue segmentation faults (Bus errors and alike are valid too).
The HSHR can only be claimed on identified releases. 
A developer cannot apply for HSHR for segfaults on his/her own code.

Here is the list of the brave fellows:

	and having a second non serial rig open.
