don't do inspect things in optimized mode (-O)

[JensTimmerman]

just importing fancylogger spends 30% of it's time in inspect calls,
actuall logging was also spending lots of time in inspect calls.
if people want faster scripts, after they're doing debugging, -O can give them a bit of it here.

$ python -m timeit -c 'from vsc.utils.generaloption import GeneralOption; GeneralOption(go_args=[])'
10 loops, best of 3: 12 msec per loop

[JensTimmerman]

with patch:

-bash-4.1$ python -m timeit -c 'from vsc.utils.generaloption import GeneralOption; GeneralOption(go_args=[])'
10 loops, best of 3: 47 msec per loop
-bash-4.1$ python -O -m timeit -c 'from vsc.utils.generaloption import GeneralOption; GeneralOption(go_args=[])'
10 loops, best of 3: 3 msec per loop

caveat: I'm not sure if -O plays fair with timeit itself.
