Issue 34: missing includes in index/beaglequeue.cpp and utils/readfile.h

1) index/beaglequeue.cpp lacks #include <unistd.h > for unlink() function.

2) utils/readfile.h lacks #include <sys/types.h > for off_t type definition.

Compile errors under cygwin gcc-4.4.5.

Missing includes for gcc-4.4.5. Closes #34

Thanks for reporting this.
