Character Pointers in SA Inmemory Array

[rjbrown2]

Remove the char* pointers that are associated with ak_ref and ek_ref within the SA stuctures. This will aid in allowing fread/write to more easily save files.

The current default value in the SADB schema is 100 characters. We can start with this as a default.

The major portion of the code that should probably fix this is just in the template files for Maria DB where the memory is allocated.
