Renamed files so camera_library is current one

What was camera_library is now camera_library_old.  What was
camera_library2 is now camera_library.
Added RUS to ifndef identifiers in all .h files

Each .h file should begin with lines like:
#ifndef _BLAH_H
#define _BLAH_H
and end with
#endif

The identifier used in these must be different for all the files being
compiled.  To avoid a name conflict with the files that KIPR uses, I
prepended RUS_ to all the existing dentifiers.
