Subject: Only two real changes.  First, Bu::FString and Bu::FBasicString are
 in different files.  This won't affect any programs at all anywhere.  This
 will just make it easier to maintain and extend later.  You still want to
 include "bu/fstring.h" and use Bu::FString in code.

The other is kinda fun.  I created a special format for unit tests, they use the
extension .unit now and use the mkunit.sh script to convert them to c++ code.
There are some nice features here too, maintaining unit tests is much, much
easier, and we can have more features without making the code any harder to use.

Also, it will be easier to have the unit tests generate reports and be run from
a master program and the like.
