Header file rearrangement Make it so that lshlib.h is slightly more like a header file to include to use the LSH ("class G") class, and slightly less a header file for developing that class, by removing all the #includes and moving them to the one-file lshlib.cpp instead. Make audioDB-internals.h slightly more of a project header file, by including there all the headers we actually need. Remove some assert()s (which do nothing) and some Uns32Ts (-> uint32_t)
