A few more minor changes. Change exitcode to signed since in mysql, -1

is not a string of bits, but really 0 when the type is unsigned.
Sheesh. Add link from testbed_stats to experiment_resources to get
better info in showstats.

+1.144: Add link from testbed_stats to the experiment_resources record
